The 2014 Chevrolet Corvette Stingray

Chevrolet is redefining modern performance with debut of the all-new Corvette Stingray. And only a Corvette with the perfect balance of technology, design and performance can wear the iconic Stingray designation. The 2014 Corvette Stingray is the most powerful standard model ever, with an estimated 450 horsepower (335 kW) and 450 lb.-ft. of torque (610 Nm). It is also the most capable standard model ever, able to accelerate from 0-60 in less than four seconds and achieve more than 1g in cornering grip. It is expected to be the most fuel-efficient Corvette, exceeding the EPA-estimated 26 mpg of the current model.

The all-new Corvette Stingray shares only two parts with the previous generation Corvette. It incorporates an all-new frame structure and chassis, a new powertrain and supporting technologies, as well as completely new exterior and interior designs. Highlights include:

• An interior that includes real carbon fiber, aluminum and hand-wrapped leather materials, two new seat choices – each featuring a lightweight magnesium frame for exceptional support – and dual eight-inch configurable driver/infotainment screens.

• Advanced driver technologies, including a five-position Drive Mode Selector that tailors 12 vehicle attributes to the fit the driver's environment and a new seven-speed manual transmission with Active Rev Matching that anticipates gear selections and matches engine speed for perfect shifts every time

• An all-new 6.2L LT1 V-8 engine combines advanced technologies, including direct injection, Active Fuel Management, continuously variable valve timing and an advanced combustion system that delivers more power while using less fuel

• Lightweight materials, including a carbon fiber hood and removable roof panel; composite fenders, doors and rear quarter panels; carbon-nano composite underbody panels and a new aluminum frame help shift weight rearward for an optimal 50/50 weight balance that supports a world-class power-to-weight ratio.

• A sculptured exterior features advanced high-intensity discharge and light-emitting diode lighting and racing-proven aerodynamics that balance low drag for efficiency and performance elements for improved stability and track capability.

• Track-capable Z51 Performance Package including: an electronic limited-slip differential, dry-sump oiling system, integral brake, differential and transmission cooling, as well as a unique aero package that further improves high-speed stability.

2014 Chevrolet Corvette Stingray: It's Here and It's the Best 'Vette So Far

After all of the rumors, blurry leaked magazine covers and artist renderings, the 2014 Chevrolet Corvette C7 is finally here.  Ok, so is the Corvette Stingray (as it is officially called) worth all the hullabaloo surrounding it?  Short answer, yes.  Long answer, absolutely, positively, without a doubt, yes.  But, as LeVar Burton was fond of saying in Reading Rainbow, you don't have to take my word for it.  The design and specs can speak for themselves.

2014 LT1 V8 from the Corvette Stingray

Let start with the most important bit, the powerplant.  The 2014 Corvette Stingray is still powered by a 6.2 liter LT1 V8 engine, but now it is churning out an estimated 450 horse and 450 lb-ft of torque.  450 & 450 for the base Corvette.  Yeehaw!  At 2,000 rpm when other cars, such as the Ferrari 458 Italia and the Porsche 911, are putting out about 200 lb-ft, the Corvette's LT1 is cranking at 400, an increase of about 50 lb-ft over the C6.  That's quite a bit of grunt.  While there's no word on the base C7 Corvette's weight, we do know that it will sprint from 0 to 60 mph in under four seconds.  The prevailing wisdom puts that number closer to 3.7 or 3.8 seconds.  Yeehaw, again!  And, you can have flawless 0-60 runs all day long because the 2014 Corvette has launch control.  Yeehaw, a third time! 

And, it sounds good too.  The exhaust diameter has grown from 2.5 inches to 2.75 inches over the last generation and is far less restrictive to the tune of a 13 percent improvement on the standard exhaust and 27 percent on the active exhaust system.  A pair of butterfly valves refine the exhaust note further when cruising in V-4 mode through the cylinder deactivation.  By the way, I'm not entirely sure that true cylinder deactivation has ever really played well with a manual transmission.  I look forward to seeing it work here.

Did I mention it should get nearly 30 mpg?  Not too bad for a car that will give the Millenium Falcon a run for its money.  The fuel efficiency comes due to the integration of a few new-to-Corvette technologies.  For the first time, Active Fuel Management, cylinder deactivation, continuously variable valve timing, an advanced combustion system that will deliver more power with less fuel, direct injection, less overall weight and better aerodynamics all contribute to give the Stingray the Corvette's best ever fuel economy. 

All the power, torque and crazy fuel saving technologies mean little if you can't get the generated power to the wheels.  That's where the new -->TREMEC TR6070 seven-speed gearbox with Active Rev Matching comes into play.  There have been a few cars where the engine's CPU will automatically match the revs on a downshift.  It was a big deal with the current iteration of the Camaro a few years back, if you recall.  The C7 will actually rev match on both upshifts and downshifts, a first.  The Corvette's brain will actually "sense" which gear the driver is shifting into and match the revs accordingly on the fly.  No more throttle blipping.  If stick shift isn't your thing, a Hydra-Matic 6L80 six-speed automatic with steering wheel mounted paddle shifters is also available.

Now that the power is to the wheels, it has to get to the ground and get there in such a way that you stay on the road.  In a move that is a bit at odds with the rest of the auto industry, the 2014 Chevrolet Corvette's wheels and tires are smaller than those on the current base 'Vette.  At 18 inches in the front and 19 inches in the rear, the wheel diameters are unchanged.  However, at 8.5 inches in width up front and 10 inches out back, the Michelin Pilot Super Sport tires are an inch and two inches narrower, respectively.  The helps the car in two main ways, better road feel and better aerodynamics.  Overall grip should stay the same due to a stickier rubber on the Pilot Super Sports.

On the road, Chevrolet has added the creatively named Drive Mode Selector that tailors 12 vehicle attributes (active fuel management, automatic shift points, throttle, steering effort, Magnetic Ride Control suspension compliance, exhaust note and stability/traction control intervention points, etc, etc). to the driver's driving needs and wants at any particular moment.  The Drive Mode Selector has five modes, Weather, Eco, Tour, Sport and Track.  Each has differing and customizable degrees of vehicular freedom and electronic nannying.  The Drive Mode Selector is operated through a twitsty knob very conveniently located just aft of the gear shift lever.

In keeping with the 2014 Stingray's trend of trying to anticipate a driver's needs, the Drive Mode Selector also changes the information the driver gets on their gauge cluster.  In Tour, Eco and Weather modes, the display shows info for trip data, audio and navigation.  Sport mode shows traditional sports car gauges.  Track mode is trying to be straight up racecar with a lap timer and everything.

The 2014 Corvette Stingray is quite the handler, too.  It will hit 1g on the skidpad.  That is thanks to some serious thought put into the cars overall design as it relates to handling.  The new Corvette's wheelbase is about an inch longer than the C6 with its front a rear tracks stretching about an inch each.  Not only does this offer a more stable feel on the road, but the turning radius has shrunk about two feet.  The new Corvette is a model of maneuverability.

As standard, the C7 comes equipped with 35mm-piston Bilstein monotube shocks that connect to dual-path aluminum shock mounts.  Opt for the Z51 Performance Package and you get 45mm-piston Bilstein dampers.  For those who go all in, the Z51 is available with the third-generation Magnetic Ride Control that is 40 percent faster reacting than in previous generations, enabling improved ride comfort and body control.

The new electric power steering system allows for variable effort, feel and ratios depending on driving situation.  Also, due to a steering column increase in stiffness of 150 percent and a shaft torsional increase in stiffness of 600 percent, the new steering system is five times stiffer overall, and hopefully more precise, than in the C6.

Going faster means you need to be able to stop.  The 2014 Chevrolet Corvette comes standard with Four-piston fixed caliper Brembo brakes derived from racing.  Up front, 13.3 inch rotors and 12.6 inch in the back.  Stopping distance has been improved by nine percent from the C6 to the C7.  With the Z51 Performance Package and you get dual-cast, slotted 13.6-inch front rotors and 13.3-inch slotted rear rotors.

It can pretty much go without saying that the past few generations of Corvettes have had somewhat lackluster interiors.  As a matter of fact, they were downright cheesy.  Thankfully not anymore.  The designers were given a blank slate to change all that.  The new interior is a very driver oriented spaces full of Napa leather with fine stitching, carbon fiber, micro-suede, real aluminum trim (not that painted plastic crap) and is fully-wrapped in soft surfaces.  So much better.  As a matter of fact, according the GM, the new interior tested better in focus groups than that of the Audi R8 and Porsche 911.  

The seats are better too.  Two options of seats are available, both on ultra-light magnesium frames.  The GT seat is designed for all-around comfort and the Competition Sport seat has serious bolsters to finally offer support on the track commensurate the Corvette's performance.  So far, the 2014 Corvette's interior can come in black, gray, red and Kalahari brown.

Outside, yes, it still looks like a Corvette, but it finally looks like the Corvette we've been dreaming of.  The headlights, are far more detailed and visually dynamic than those of the past.  They are almost Ferrari-like with the LEDs running up the sides.  The dual-element taillights are sure to be a point of controversy for quite a while.  The squared-off, tightly spaced lamps are a departure from the tradional lamps of old but a departure in a good direction.  The sculpted lenses stand up well to the angular and sculptural shape of the new body.

Under its beautiful beautiful skin, the Corvette is completely new.  Lightweight materials and components like the carbon fiber hood and removable roof panel, composite fenders, doors and quarter panels, carbon-nano composite underbody panels and an aluminum frame (that is 57 percent stiffer and 99 lbs lighter than that of the C6) give the 'Vette and ideal 50/50 weight distribution.

Hopefully the 2014 Chevrolet Corvette be as good in the real world as it is on paper.  We'll just have to wait and see.  The Stingray is scheduled to hit dealerships sometime around September.
