2015 Chevy Corvette Review

The 2015 Corvette gets an eight-speed automatic transmission option (replacing last year's six-speed), upgraded OnStar functionality with a 4G LTE data connection and mobile Wi-Fi hotspot capability, an available Performance Data Recorder with in-car video and a handful of minor trim changes. Did we miss anything? Oh, there is the minor detail of the all-new 650-horsepower Z06 model debuting this year as well.

With its improved automatic transmission and reinvented, ridiculously fast Z06 variant, the 2015 Chevrolet Corvette bolsters its credentials as the world's best performance-car bargain.

The current-generation Chevrolet Corvette isn't exactly a car that was crying out for major improvements. When the latest, redesigned model (the "C7") debuted last year, we heralded it as "the most complete and refined Corvette yet," with so much power that it's as if "Chevy secretly strapped a rocket engine underneath the car." But the 2015 Chevrolet Corvette lineup sees the new-generation Z06's debut -- in both removable-roof coupe and soft-top convertible forms -- and we fear we're running out of analogies. If the base 455-hp V8 is a rocket engine, the Z06's supercharged 650-hp V8 is akin to the solid rocket boosters that gave liftoff to the Space Shuttle. For thousands less than a base Porsche 911 with no options, the 2015 Corvette Z06 will outrun almost any car in the world.

Naturally, the Z06 also provides suspension and braking upgrades that take the C7's already astounding dynamics to new heights. But the improvements for 2015 aren't limited to this low-volume supercar variant. More relevant to most shoppers is the introduction of an optional eight-speed automatic transmission across the lineup (including the previously manual-only Z06), replacing the lackluster six-speed automatic that carried over last year from the previous C6 generation. There are a couple gotta-have-it tech upgrades for 2015 as well, namely a 4G data connection with WiFi hotspot capability and a Performance Data Recorder that produces data-rich driving videos via a front-facing 720p camera in the rearview mirror housing.

But the new Corvette's fundamental excellence continues to be the real story, from its vastly improved interior to its unprecedentedly capable -- and approachable -- handling. You can even squeeze 30 mpg out of the base engine on a highway cruise if you try hard enough. The newest generation, which we learned during a 27,000-mile long-term test of a 2014 Corvette, also doesn't feel like it was built to a price; it just feels world-class in practically every respect.

Sizing up the Corvette's competition, it's hard to think of a premium sporting car that's not fair game. The 2015 Porsche 911 can claim greater versatility (thanks to its tiny rear seats) and a heightened sense of overall design harmony, but you'll be paying a lot more for less performance. You could probably say the same about the new 2015 BMW M4, but it's not as engaging to drive and its pricing with desirable options has crept up into Z06 territory. The 2015 Mercedes-Benz C63 AMG coupe is on a farewell tour with its epic 6.2-liter V8, yet it lacks the visual impact of the 'Vette. As for the 2015 Dodge Viper and 2015 Nissan GT-R, they cost more and deliver less than the Z06. The 2015 Corvette is a juggernaut that's not to be missed if you're fortunate enough to be shopping for this kind of car.

The Corvette Stingray and Stingray Z51 are powered by a 6.2-liter V8 that drives the rear wheels. Maximum standard output is 455 hp and 460 pound-feet of torque, while the optional performance exhaust bumps those numbers to 460 and 465, respectively. A seven-speed manual (with automatic rev-matching) is the default transmission, with an eight-speed automatic also available. Both transmissions feature a launch control mode.

EPA-estimated Corvette fuel economy is a remarkable 21 mpg combined (17 city/29 highway) with the manual transmission. The automatic returns a virtually identical 20 mpg combined (16 city/29 highway).

The Corvette Z06 steps up to a supercharged 6.2-liter V8 that cranks out 650 hp and 650 lb-ft of torque. The same two transmissions are offered, marking the first time an automatic has been available on a Z06. Equipped with the manual, the Z06 rates an EPA-estimated 18 mpg combined (15 city/22 highway), whereas the automatic earns figures of 16 mpg combined (13 city/21 highway).

In Edmunds performance testing, a Stingray Z51 coupe with the manual transmission accelerated from zero to 60 mph in just 4.1 seconds. The automatic was even quicker, at 4.0 seconds. Chevy says that early Z06 tests indicate that 60 mph arrives in about 3 seconds flat, with the quarter-mile passing in an astonishing 11 seconds.

Standard safety features on the 2015 Chevrolet Corvette include antilock disc brakes, traction and stability control, side-impact airbags and a rearview camera. Also standard is OnStar, which includes automatic crash notification, on-demand roadside assistance, remote door unlocking and stolen vehicle assistance.

In Edmunds brake testing, a Stingray Z51 coupe with its upgraded brakes needed just 93 feet to stop from 60 mph, the shortest distance we've ever recorded.

The naturally aspirated V8 in the 2015 Chevrolet Corvette Stingray is so powerful and flexible that it's a dream engine in its own right. Midrange torque is prodigious and, should you put the hammer down, you'll be at redline before you know it. That spirited performance is accompanied by a glorious symphony trumpeting from the exhaust's quad tailpipes, should you opt for the dual-mode exhaust.

There just aren't any weaknesses in this motor, and the new eight-speed automatic actually amplifies its performance, upshifting so quickly that accelerating through the gears feels like a single seamless surge. Downshifts are swift and perfectly rev-matched as well. Oddly, it's not quite as razor-sharp when shifted manually, as there can be a noticeable lag after the paddle flick before the downshift occurs. Overall, however, any Corvette Stingray is a bona fide thrill machine.

When you replace "Stingray" with "Z06," things just get crazy, as in crazy-fast. We've yet to fully test it, but it's fair to assume that acceleration will be utterly explosive at all times. Only a handful of exotics can match the Z06's performance.

Either way, the 2015 Corvette's steering provides excellent feel and response, while grip is extraordinary from the base tires and just gets better from there. The adjustable traction and stability control systems also allow drivers to approach the car's handling limits safely. At the same time, even track-ready Corvette models are eminently comfortable long-distance tourers or golf course shuttles, and they can even serve as grocery carts in a pinch. If you're after a sports car for all occasions, it's hard to do better than a 'Vette no matter how much money you have to spend.

Cabin design and quality have been Corvette foibles for decades, but not anymore. With the C7, Chevrolet made a concerted effort to bring the 'Vette's interior up to snuff. The cockpit is more driver-centric now, with a sharply canted center stack that creates a jetfighter-like vibe. Materials quality is, for the most part, very good, although little things like the flimsy-feeling engine starter button allow Porsche's 911 and Boxster/Cayman to keep the lead for interior refinement. We do like the seats, which provide firm, well-shaped support in all driving scenarios -- particularly with the optional power side bolsters. The available sport seats add even more lateral snugness.

A dial on the center console of every 2015 Corvette lets you choose from five different drive modes (Weather, Eco, Tour, Sport and Track) that tweak steering, throttle, transmission and stability-control calibrations, depending on trim and equipment. The standard 8-inch touchscreen display utilizes Chevrolet's latest MyLink electronics interface, which includes smartphone integration for useful apps like Pandora and Stitcher. There's also a cool 8-inch customizable display in the gauge cluster that has a different layout for each drive mode you select. Both are valuable additions that make the 'Vette feel thoroughly up to date, although the center touchscreen can occasionally be slow to respond and/or prone to glitches.

Corvette owners have long enjoyed the coupe's generous hatchback storage, and that tradition continues with the coupe's 15-cubic-foot cargo area, which offers plenty of room for luggage, groceries, golf bags and what have you. As for the convertible's conventional trunk, it's pretty generous by drop-top standards, checking in at 10 cubic feet.
