Chevrolet Corvette Review

Often referred to as America's only true sports car, the Chevrolet Corvette is one of the world's best known and longest-running nameplates. Oddly, it had a rather humble beginning, starting life back in 1953 with a straight-6 engine and a two-speed automatic transmission. The first few years saw the fiberglass-bodied two-seater from Chevrolet earn praise for its handling but criticism for its relatively tame performance. (At the time, it was soundly outgunned by a variety of European sports cars in terms of performance.)

Thankfully, a V8 engine option debuted in 1955, and by the late '50s, the Chevy Corvette could hit 60 mph in less than 6 seconds. The intervening decades have seen the Corvette pass through multiple generations. Each decade has brought its own Corvette theme, including the muscle-bound '60s, the highly stylized '70s and the electronically aided '80s. More recently, the Corvette has improved enough in the refinement department that many finally consider it worthy to compete against the world's best.

Highlights of the Corvette's timeline include the '57 Fuelie (the nickname for the optional fuel-injected 283 V8), the '63 Sting Ray split-window coupe, the '65-'67 big blocks (427-cubic-inch V8s), the high-revving LT-1s of the early '70s, the ultra-high-performance ZR-1s of the early '90s and the fast yet user-friendly C5s (fifth generation) of the late '90s. Of course today's Corvette, an outright bargain when compared to sports cars from Europe, should be acknowledged as well. The current Corvette offers the performance of an all-out exotic at a third to a quarter of the price.

Current Chevrolet Corvette

Debuting in 2005, the current Chevrolet Corvette (known as the C6) is by far the best yet. As with past Vettes, a coupe and convertible are offered. Performance is exceptional, with the 0-60-mph sprint taking less than 5 seconds, the quarter-mile taking less than 13 and top speed in excess of 180 mph. That's for the standard Corvette. The Z06 version is even more thrilling, hitting 60 in the low 4s, the quarter in the low 12s and running on up to a top end approaching 200 mph. The standard Corvette comes with a 6.0-liter, 400-horsepower V8 coupled to either a six-speed manual or optional six-speed automatic. The Z06 comes with a 7.0-liter V8 with 505 hp mated to a six-speed manual.

The newest Chevrolet Corvette is equally impressive in terms of its improved build quality and increased daily driver usability. The cockpit boasts friendly ergonomics, supportive seats and excellent fit and finish. As before, the car's hatchback body style provides massive cargo capacity, which stands at 22 cubic feet in the coupe. A choice of three suspensions (standard, optional Magnetic Ride Control with Sport and Touring modes and track-ready Z51) for the regular Corvette mean there's a setup for everyone, from casual enthusiasts to hard-core apex clippers -- and all provide a fairly smooth ride. The Z06, in spite of its immense capabilities, is still docile enough to handle the daily commute without making the driver grit his teeth every time he faces stop-and-go traffic or a rough section of pavement.

In reviews from our editors and posted consumer commentary, the C6 garnered high marks and universal praise for its combination of strong performance, razor-sharp handling, comfortable ride, eye-catching style, affordability and relatively impressive fuel economy. Complaints were minor in comparison, centering on the manual transmission's clunky gearchanges, along with the cabin's mediocre cupholder and storage provisions, ho-hum interior materials and underwhelming Bose audio system.

Past Chevrolet Corvette Models

The previous Corvette (the C5) was built from 1997-2004 and marked the Corvette's transition from a capable but flawed (in terms of comfort and ergonomics) to world-class sports car. Easier to get in and out of than the C4, the C5 also boasted a new chassis that had nearly 50/50 weight distribution between the front and rear axles, a more compliant suspension, a much roomier cockpit with more supportive seats and a new "LS1" 5.7-liter V8 that made 345 hp. The transmission choices were a six-speed manual and four-speed automatic.

With a 0-60-mph time of fewer than 5 seconds and a top speed of around 175, there wasn't much that could touch this Vette short of a few big-dollar exotics from Europe. That first year saw just the hatchback body, whose styling drew barbs for its rather large hindquarters. But the benefit of the big butt was more than 20 cubic feet of cargo capacity under the rear hatch. A convertible joined the lineup for '98 and the following year brought a fixed-roof coupe. For 2001, the mighty Z06, a reincarnation of an earlier "Z06" performance package from the '60s, debuted, bringing 385 hp to an already impressive chassis. As if that weren't enough, the Z06 gained 20 hp the very next year.

Enthusiasts looking for a sports car they can live with day in and day out would be well advised to seriously consider a Chevy Corvette from this generation. Pros and cons are mostly similar to the current generation, and although the C5 has been criticized for spotty build quality, this Corvette still offers the most bang for the buck in the used sports car marketplace.

The fourth-generation Chevrolet Corvette, or C4, is the other model that non car-collectors will likely be interested in. It was available for the 1984-'96 model years. The flamboyant style of the previous generation was replaced with a leaner look, and a racetrack-ready suspension featuring lightweight alloy components debuted as well. First-year cars should be avoided, as the 5.7-liter V8 made just 205 hp with its troublesome "Crossfire Injection" setup, while the suspension was much too stiff for daily driver duty. Subsequent years saw the debut of a convertible, more power and suspension refinements. By 1990, the Corvette was a well-sorted sports car with precise handling and respectable performance from its 250-hp engine. That year also saw the debut of the ZR-1 supercar, which could run the quarter-mile in the low 13s and hit a top speed of around 175 mph, thanks to its 375-hp, 5.7-liter V8. For '92, the standard Corvette gained more power via the 300-hp LT1 V8. The ZR-1's output shot up to 405 hp for '93. The last year of this Corvette's generation saw the availability of a 330-hp version of the LT1 V8.

Although the C4 is regarded as desirable in terms of performance for the price, its awkward ingress/egress, cramped cockpit and stiff ride make it a weekend toy for all but the most ardent enthusiasts.

Cadillac XLR-V Review

There are a few lucky car shoppers out there who can afford the very best the automotive world has to offer. For those hoping to go really fast and be coddled while doing it, Cadillac created the XLR-V convertible. The V at the end of the car's moniker indicates that it's a performance variant of Cadillac's XLR, but it could easily stand for viciously quick and very luxurious.

2008 Cadillac XLR-V Base Convertible

Viciously quick comes courtesy of this Cadillac's supercharged V8, which will send you hurtling from zero to 60 in less than 5 seconds. You won't find any assembly lines at the Wixom, Michigan, facility in which the high-performance engine is made. Taking a cue from European ultraluxury manufacturers, Cadillac has given each V8 a personal touch, with each being built from start to finish by a single craftsman. Very luxurious is the end result of the wealth of standard features offered by the Cadillac XLR-V roadster. Satellite radio, keyless ignition and a voice-activated navigation system are all part of the lineup.

The XLR-V's features list brims with opulence, but unfortunately, the same can't be said for its cabin. Abundant wood and metallic accents are a good start, but aesthetics ultimately miss the mark, thanks to generic-looking switchgear and unspectacular leather. For a car that costs about $100K, this is a profound disappointment. Cabin dimensions in this convertible are also tight, resulting in a cramped environment for taller drivers. Another shortcoming is the car's lack of cargo room.

It should also be said that while the Cadillac XLR-V offers a memorable and engaging ride, you'll find more refined driving dynamics in its European competition. Still, for those seeking a less common American alternative, this singular Caddy could prove to be a pleasing choice.

Current Cadillac XLR-V

Designed to facilitate wind-tousled tresses and sun-kissed cheeks, the Cadillac XLR-V is available only as a two-seat convertible with a retractable hardtop. Aside from its high-performance innards, this V is distinguished from its less spirited sibling by virtue of styling cues like a unique front grille and a sculpted hood designed to accommodate the V8's supercharger.

Only one trim is available, but -- as befits the car's nearly six-figure price tag -- it's fully loaded. Perks like Bluetooth phone connectivity, heated leather seats and adaptive cruise control (which automatically maintains a preset distance between the roadster and the car ahead of it) are all standard. The XLR-V's power-retractable hardtop can go from closed to open (and vice-versa) in about 30 seconds.

Pop this Caddy's rather menacing hood and you'll find a supercharged 4.4-liter V8 with the goods to kick out 443 horsepower and 414 pound-feet of torque. A broad torque band keeps this might readily accessible; the engine is able to deliver 90 percent of peak torque between 2,200 and 6,000 rpm. A six-speed automatic transmission with manual-shift capability directs power to the rear wheels.

The Cadillac XLR-V's cabin is attractive, but attractive simply isn't good enough for a car in this price range. Aluminum accents add a nice gleam to the steering wheel and instrument panel, and there are pleasing amounts of burnished exotic wood in evidence -- you'll find it on the shifter knob, steering wheel and parts of the door and center console. But compared to what's available from other cars populating this rarefied bracket, the overall look and feel of the Cadillac's interior is a little disappointing. There's also not a whole lot of room available. The vertically gifted will find getting comfortable in the driver seat a challenge, and tight cargo room limits versatility.

Once settled, however, drivers will find themselves swept away on a wave of raw power. The car is responsive and quick, eager to leap to attention at the slightest tap of the throttle. Its Magnetic Ride Control adaptive suspension (which automatically adjusts the suspension to reflect driving conditions) is tuned to be sportier than that of the XLR, but thanks to careful attention paid to handling dynamics, the car's ride is never abusive. The only real detracting attribute is the car's steering, which we have found to be overly heavy.

Cadillac XLR Review

Yet another entry from Cadillac to show the world it's serious about competing with the top European and Japanese luxury brands, the two-seat Cadillac XLR roadster is the company's flagship vehicle. Though it shares the same platform as the current Corvette, the XLR variant is not a simple case of corporate badge engineering. It's more of a grand touring machine than a hard-edged sports car, as the Caddy's responses are softer and comfortably refined. It also uses a more subdued 4.6-liter, 320-horsepower V8 engine rather than the Vette's edgier 6.0-liter, 400-hp V8 power plant.

2008 Cadillac XLR Convertible

The use of lightweight components like aluminum suspension pieces and composite body panels keeps the Cadillac XLR from being a bloated luxury two-seater. In addition, the standard Magnetic Ride Control adaptive suspension system automatically firms up or softens the suspension based on driving conditions, ensuring generally smooth and responsive maneuvers. The combination of bold, angular styling outside and distinctive eucalyptus-wood cockpit accents gives the XLR a sophisticated presence. Further, the XLR's power retractable hardtop roof allows the comfort and security of a coupe when the top is raised.

As impressive as it is, the Cadillac XLR roadster is not quite the "standard of the world" just yet. Though its styling and Cadillac badge will appeal to those looking to roll up to the valet in something different from the status quo, the XLR comes up short in terms of maximum performance and interior detailing when compared to its German rivals. But if those qualities aren't your top priority, and you're not overly impressed with the rest of the XLR's competition, this Cadillac convertible is worth considering.

Current Cadillac XLR

The Cadillac XLR is a two-seat luxury roadster featuring a retractable hardtop roof. The standard XLR comes with just about all of the luxury features you'd expect, including 18-inch alloy wheels with run-flat tires, adaptive xenon HID headlights, heated leather seats with plenty of power adjustments, dual-zone automatic climate control, keyless startup, a head-up display, a navigation system and a Bose audio system with satellite radio and a CD changer. There are also a couple special variants, the Passion Red Limited Edition XLR and the Platinum Edition XLR, that feature unique exterior paint and other minor trim enhancements.

A refined yet muscular 4.6-liter V8 powers the XLR, and a six-speed automanual transmission transmits the Northstar V8's 320 horsepower and 310 pound-feet of torque to the rear wheels. We've found the XLR to be a spirited performer, with 0-60-mph sprints taking less than 6 seconds and high-speed cruising that's generally hushed and effortless. Full-throttle shifts result in little hesitation, and the sound of the engine at speed is as good as or better than any V8 in its class. Antilock disc brakes are standard safety items, as are run-flat tires, a tire-pressure monitor, stability control, head/torso side-impact airbags and rear parking sensors.

Inside, the Cadillac XLR boasts an upscale cabin complete with rich eucalyptus wood trim and aluminum accents in addition to comfortable leather seating -- altogether clean-looking, modern and warm. State-of-the-art technologies abound, too: A head-up display shows vital information such as speed, fuel level and audio status on the windshield, adaptive cruise control automatically maintains a preset distance between the XLR and the car in front, and a large touchscreen mounted high in the center stack helps keep the dash free of numerous single-use buttons. Our editors found fit and finish to be excellent, save for a few pieces of metallic trim that seem tacked-on rather than cleanly integrated.

As fast as the XLR is when pushed, those expecting a true Cadillac sports car will be disappointed. Acceleration, though certainly quick, is not as forceful as its corporate cousin, and the XLR's softer suspension tuning results in noticeable body roll during hard cornering and plenty of nosedive under heavy braking. Even with its adaptive suspension's split-second response, the Cadillac XLR still feels less willing to tackle turns than the more athletic European contenders. On the open highway, the roadster hits its stride, delivering an undisturbed ride with effortless tracking.

Cadillac STS-V Review

In a luxury sport sedan market that's traditionally dominated by German carmakers, the Cadillac STS-V makes a tremendous impression. A model from Cadillac's V-Series line of ultra-performance vehicles, the STS-V is based on the STS large sedan. With its supercharged V8 producing 469 horsepower, it's the most powerful car Cadillac has ever produced. The car also comes with upgraded hardware for improved handling and braking and minor styling changes to differentiate it from regular STS models.

2007 Cadillac STS-V Sedan Shown

The focus on performance doesn't come at the expense of luxury. Just like the standard version, the V-Series sedan is comfy, plush and loaded with a generous amount of premium features. Overall, we're quite impressed. Though the Cadillac STS-V doesn't quite match some competing models in terms of maximum performance or prestige, we still think it's a very viable choice for a big-bore luxury sport sedan.

Current Cadillac STS-V model

A special-edition, high-performance vehicle, the Cadillac STS-V sedan is available in one trim level only. (Cadillac says it limits production to help exclusivity.) Standard equipment highlights include heated front and rear seats, a navigation system and a 15-speaker Bose surround-sound audio system with a six-CD changer.

Distinguishing the STS-V from the standard STS are larger wheels (18-inchers in front and 19s in the back), massive Brembo brakes, a larger front grille for improved airflow, additional brake ducts, and additional aerodynamic and stylistic enhancements.

For motivation, the rear-drive STS-V is equipped with a supercharged 4.4-liter V8 engine that pumps out a startling 469 hp and 439 lb-ft of torque. Zero to 60 is accomplished in 5.1 seconds. A highly responsive six-speed automatic transmission (with manual shift control) is standard.

But the Cadillac STS-V is world-class in ways beyond its under-the-hood muscle. It has been outfitted with a sport-tuned suspension. And compared to a standard STS, V-Series sedan's steering is quicker. The result is that it handles like a car half its size while providing meaningful feedback to its driver. A limited-slip differential, antilock brakes, stability control and traction control are all standard on the STS-V. Other safety equipment includes front-seat side airbags and full-length head curtain airbags. A tire-pressure monitor and rear park-assist system are also standard.

The STS-V's long wheelbase means there's generous legroom in the front and back. The interior is upscale and handsome, with finely stitched seats and accents of wood and aluminum, though it's still not quite at the top level of quality found in some European luxury sedans. The trunk is also smaller than what one might expect for this class of car.

In reviews, our editors found the Cadillac STS-V to be powerful in every situation. It rockets off the line, but the real allure is what happens afterward. Passing power on the highway is effortless and easy. And even when you don't have the accelerator pedal pinned, the STS-V's handling abilities make it fun to drive. It's true that it's a bit out of its element on tight, twisty roads. This isn't a downfall, but rather an inherent characteristic of its size and genre. In general, the STS-V strikes an excellent balance between high-performance capability and everyday luxury driving.

Cadillac STS Review

Though it has grown into an entirely different species, the luxury performance DNA of the Cadillac STS can be traced all the way back to the special range-topping Seville hardtop coupe of the 1950s. At that time one of the fastest, flashiest and most luxurious cars on the road, it evolved and re-emerged several decades later as the buttoned-down Seville luxury sedan, capable of sharing company with Europe's finest.

2008 Cadillac STS Luxury Sedan Shown

Handsome, contemporary styling, tighter build quality and a new high-performance STS sport model set the stage in the early 1990s, and the addition of a sophisticated and powerful new DOHC Northstar V8 engine and detail refinements throughout the decade made the most of -- and tended to somewhat mask -- its limiting front-drive architecture, the STS's one performance Achilles heel. As it entered the new millennium, however, Caddy's flagship had aged and lost some of its appeal as trimmer, more sophisticated, and in most cases, rear-wheel-drive European and Japanese competitors overtook it in terms of refinement and performance.

Evolution gave way to revolution in 2005 as Cadillac dropped the Seville moniker in favor of its alpha-centric naming strategy, coinciding with a quantum leap forward in technology, build quality and overall refinement. Based on GM's global Sigma rear- and all-wheel-drive platform and utilizing powerful new V6 and Northstar V8 engines, the Cadillac STS is once again capable of taking on all comers.

If you're in the market for a finely tailored luxury sedan with the power, roominess, comfort and value to outpace many of its smaller German and Japanese rivals, we recommend that you take a serious look at the Cadillac STS.

A full-size luxury sedan in its physical dimensions, the Cadillac STS is priced in line with premium midsize sedans and available with a V6 or V8 engine. Common features on all models include leather seating, 17-inch wheels, dual-zone climate control, a Bose sound system and OnStar. Popular options include a navigation system, a head-up display and heated/ventilated front seats grouped in two available Performance and Luxury trim packages.

The two available engines -- a surprisingly responsive 3.6-liter V6 rated at 255 horsepower and 252 lb-ft of torque, and a 4.6-liter Northstar V8 that generates 320 hp and 315 lb-ft of torque -- both feature variable valve timing and electronic throttle control. A five-speed automatic transfers power from the V6, and a six-speed automatic helps V8-equipped STSs achieve impressive acceleration and fuel economy for this class.

In reviews and road tests, our editors have found the strengths of the Cadillac STS to be its nimble road manners, powerful engine options and high-quality audio system. Downsides include an interior that lacks the quality of materials found in competing high-dollar sedans, along with seats that some might find overly firm.

Those in search of a satisfying balance of performance and economy may want to focus on the basic V6/rear-drive model, while STS shoppers looking for maximum performance in all conditions can lean toward the all-wheel-drive V8 version. No longer hampered by the compromised front-drive layout of old, all STS owners now enjoy world-class performance and value fully competitive with the best of the rest from around the globe.

The Cadillac STS officially debuted for the 2005 model year. Only minimal changes have occurred since. Those interested in a used model previous to this date will want to check out the front-wheel-drive, fifth-generation Seville-based model produced from 1998-2003.

BMW Z4 Review

The BMW Z4 is one of the more intriguing sports cars currently available. It's known for its engaging handling and steering, thrilling inline six-cylinder engine and distinctive styling. Although its stated horsepower ratings are equaled or surpassed by those of some less expensive machinery, the Z4 counters with a lighter curb weight and, in most cases, a more rewarding driving experience. Recent improvements have made the latest Z4 the best yet, and older models are still a very viable choice for a used sports car.

The BMW Z4 is built at the company's Spartanburg, South Carolina, facility, and has been in production since the 2003 model year. It's a successor to the original Z3 and is the company's only two-seat sports car. It features traditional characteristics such as a front-engine/rear-drive layout, a hunkered-down stance, a long hood and rearward positioning of driver and passenger. Another notable element is the car's chiseled exterior design, which BMW says is used to add tension to the car's shape.

The BMW Z4 is available as a roadster with a convertible top or a fixed-roof coupe. For the roadster, there are two trim levels: 3.0i and 3.0si. The Z4 3.0i comes with features such as 17-inch wheels, stability control, antilock brakes, power mirrors and windows, manually operated seats and vinyl upholstery. A 3.0-liter inline six-cylinder engine rated at 215 horsepower is standard, as is a six-speed manual transmission. A six-speed automatic is optional.

The Z4 3.0si features 18-inch wheels, a few upgraded interior features and a 255-hp 3.0-liter inline six. A few options are also available for both trim levels, including a Premium package with a power-operated top and a Sport package designed to improve the vehicle's handling capabilities. The Z4 Coupe is offered in the 3.0si trim only.

Even without the Sport package, the Z4 rewards drivers with an engaging driving experience. In Edmunds.com reviews of the BMW Z4, editors have praised the car's sharp reflexes and quick acceleration. The Coupe possesses a slight advantage in terms of handling due to its added body rigidity. For shoppers desiring even more performance, there's also an M-powered version of the Z4.

Because of a major update for 2006, Z4 models from this year and onwards are a better choice than earlier models, if price is no object. This update included the mid-year release of the coupe body style, the 215-hp and 255-hp engines, and the six-speed automatic. Other changes to the BMW sports car included a retuned standard suspension for better ride quality, a higher final-drive ratio for improved acceleration, new wheel designs, additional braking functionality for the stability control system, updated front and rear styling and minor interior trim updates.

From 2003-'05, BMW Z4 models were identified as either 2.5i or 3.0i. The 2.5i has a 2.5-liter, inline six-cylinder engine that makes 184 hp, while the 3.0i uses a 3.0-liter straight six that generates 225 hp. For transmissions, there is a five-speed manual (standard on the 2.5), a six-speed manual (standard on the 3.0), a five-speed automatic or, as on the M3, a six-speed Sequential Manual Gearbox (SMG). There were a few minor changes made during this period in terms of feature content, but none of them were significant enough to make one model year more desirable than another.

Aston Martin DBR 9

The Aston Martin DBR9 is a racing car by Aston Martin Racing, first built in 2005. The name DBR9 is derived from the original 24 Hours of Le Mans-winning DBR1 car, named for then-owner David Brown, which not only won the 24 Hour race in 1959 but also the World Sportscar title.

Based on the Aston Martin DB9 road car, the DBR9 retains the chassis, and the engine block and cylinder heads of the road car's V12 engine. The rest of the car is re-engineered for high performance competition use. The DBR9's bodywork is a blend of optimum aerodynamic performance and the styling of the DB9 road car. All the body panels are constructed from carbon fibre composite (except the roof) to minimize the weight of the car. To complete the aerodynamic body, the bottom of the car is flat all the way from the front to the rear diffuser. To optimise rear downforce a carbon fibre wing has been added. The car goes from 0-60 mph in 3.4 seconds.

For the 2007 24 Hours of Le Mans, Prodrive made modifications to the DBR9 design in order to not only improve performance, but also to increase driver comfort in the cockpit. Due to new regulations put into place by Le Mans organizers, the DBR9 required the installation of an air conditioning unit in order to prevent overstressing drivers. Prodrive went further by putting a heat-resistant white roof on all new cars to assist in keeping cockpit temperatures down. Performance modifications included the removal of two cooling vents from the bonnet of the car due to no longer being necessary.
