THE GREATEST CORVETTE EVER Chevrolet has redefined the modern performance two-seat sports car with the all-new Corvette Stingray featuring…

 

 

 

a perfect balance of technology, design and performance that now wears the iconic Stingray designation. The 2014 Corvette Stingray is the most powerful standard Corvette model ever with 455hp and 460lb.ft. of torque-and 460hp and 465lb.ft. of torque with the optional performance exhaust system.  It is also the most capable standard Corvette with Z51-equipped models able to accelerate to 60mph from a standstill in just3.8 sec, run the ¼ mile in 12sec. at 119mph, plus achieves 1.03g in cornering grip and stop from 60mph in just 107ft.  Furthermore, the new Corvette Stingray backs its performance capability with the greatest efficiency of any sports car on the market, delivering an EPA-estimated 17mpg/city and 29mpg on the highway with the all-new seven-speed manual transmission.  No other car offers more than 465hp and greater than 29mpg on the highway.  The all-new Corvette Stingray shares only two parts with the previous-generation C6 Corvette.  It incorporates an all-new frame structure and chassis, a new powertrain and supporting technologies and a completely new exterior and interior design.  The Stingray coupe starts at $51,995.00, including destination, and the Convertible is priced from $56,995, including destination.  They share identical chassis tuning and performance technologies.  They also share nearly identical curb weights, as the only structural changes for the convertible are limited to accommodations for the folding top and repositioned safety belt mounts.  The all-new convertible top can be lowered remotely using the key fob and operates at up to 30mph.

Corvette Stingray’s provocative exterior styling is as functional as it is elegant.  While no single detail is repeated from previous generations, the new Corvette Stingray include the distinctive profile defined by a long dash-to-axle ratio-a low, lean proportion emphasized even more on the-and the greenhouse evoking the canopy of a fighter jet with dual-element taillights.  For the new Corvette to be called a Stingray, it had to deliver an incredible, purposeful visual impact-just as the original did in 1963.  That visual impact is evident in fighter jets and the Stingray animal itself.  Their beauty comes from their purpose, designed to cut through air or water as quickly and efficiently as possible.  Lighting is a signature element of the Stingray’s design and reinforces its high-tech aesthetic.  At the front indirect white LED lamps from a distinctive daytime styling cue.  There are set in black-chrome lamp housing with standard HID project headlamps.  The turn signals feature edge-lit amber LED lighting.  All-new, dual-element taillights represent the greatest departure from tradition and are among the car’s most dramatic elements.  The three-dimensional, sculpted lenses house indirect LED lighting.  The state-of-the-art lighting uses hidden LED lamps that cast their light up from the bottom of the housing into a reverse reflector, creating an even glow.  LED lamps are also used for the white backup lamps.  The taillamps integrate functional aircraft-style air outlets for the optional differential and transmission coolers.  From the front or rear, the signature lighting brings the new Corvette to life; it looks beautiful, intriguing and more than a little intimidating.  It gives the Corvette a nighttime appearance unlike anything else on the street.
When it comes to aerodynamics, the new Stingray is in a league of its own.  Advanced computer-aided modeling programs predict and track airflow over, under and through the new Corvette’s body.  Engineers and designers also relied on data gleaned from the Corvette Racing program-the most successful program ever in the American Le Mans Series and the 2012 GT class champion-to help balance front and rear grip for high-speed stability.  Many hours were spent in the wind tunnel hand-sculpting surfaces for aesthetics and performance.  Functional exterior elements on all models include a new grille/radiator arrangement, hood vents and front fender cove vents.  Venting air out of the hood reduces total front-end lift for improved steering response at high-speeds, while the fender vents relieve underhood air pressure to reduce aerodynamic drag.   
To keep weight to a minimum and strength to a maximum, the body is made of composite and carbon-fiber with a hydroformed aluminum frame with aluminum and magnesium structural and chassis components.  Corvette Stingray takes advantage of these lightweight materials using advanced manufacturing technologies and technology transfer from the Corvette Racing program to produce an ideal 50/50 weight balance and to deliver world-class power-to-weight ratios.  This technologically advanced foundation is an all-new aluminum frame structure that is 99 pounds lighter, and is 57% stiffer than previous generations.  The result is a frame that is so strong-no structural reinforcements are needed for the convertible model.   Compared to the previous generation, which used continuous hydroformed main frame rails with a constant 2mm wall thickness, the new Corvette’s frame features main rails composed of five customized aluminum segments, including aluminum extrusions and a center main rail section and hollow-cast nodes at the suspension interface points.  Each segment’s gauge varies in thickness from 2mm to 11mm tailored-along the shape-by the simulation software to optimize the strength requirements for each frame section with minimal weight.  The aluminum frame is manufactured using innovative manufacturing processes at GM’s Bowling Green, KY., assembly plant.  The state-of-the-art facility employs several advanced joining technologies to ensure dimensional accuracy within 0.75mm.  Each frame features 354 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum; 188 Flowdrill-machined fasteners, which are installed by a high-speed drill that extrudes the frame material to create a strong, integral collar that is tapped for bold-on fasteners; 113 feet of structural adhesives, used in conjunction with welding and fasteners to increase overall frame stiffness; 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.   The frame’s greater strength and lower weight are complemented by chassis elements also designed for low-mass strength, including hollow-cast aluminum front and rear cradles that are approximately 25% lighter and 20% stiffer than the solid cradles used on the previous structure.  The innovative uses of materials include a standard carbon fiber hood on all models and a carbon fiber roof panel on all coupes.  In addition, underbody panels are created with carbon-nano composite technology, an advanced blend of traditional composite material and carbon fiber for reduced weight and improved strength.  Fenders, doors, rear quarter panels and the rear hatch are made with lighter-density Sheet Molded Compound that the previous model.  The unique styling, incredible interior and all-new frame and chassis components make the all-new C7 Corvette Stingray one of the greatest two-seat sports cars on the road, but that is only half the story. The other half of the incredible all-new Corvette Stingray is the powertrain, suspension, steering, brakes and wheels/tires that make it one of the best to drive.
The lightweight elements of the Stingray contribute to the ideal 50/50 weight balance.  Combined with its SAE-certified 455hp, the new Corvette delivers a better power-to-weight ratio than the Porsche 911 Carrera and Audi R8.  Those 455 horses are generated by an all-new LT1 6.2 liter Small Block all-aluminum V8 engine which also produces 460lb.ft. of torque.  More importantly, it generates 50lb.ft. of torque more low-rpm torque than the previous 6.2 liter engine, matching the 7.0 liter LS7 engine from the 2013 Corvette Z06 from 1,000 to 4,000rpm.  The engine’s performance comes from combining advanced technologies such as direct injection, Active Fuel Management and continuously variable valve timing with an advanced combustion system.  More than 10-million hours of computational analysis went into the new Small Block’s design including more than 6-million hours along on the combustion system.  The LT1 is backed by a choice of active exhaust systems that are less restructure than the previous generation, due in part to an increase in diameter from 2.5 inches to 2.75 inches.  The standard system offers a 13% improvement in airflow and features a pair of butterfly valves that contribute to great refinement at cruising speed when the engine is operating in fuel-saving V4 mode.  An available performance variable-mode active exhaust system offers a 27% improvement in airflow.  It features two additional valves that open to a lower-restriction path through the mufflers.  When open, these valves increase engine performance and produce a more powerful exhaust note.  It also raises the engine’s output to 460hp and 465lb.ft. of torque.
The LT1 is offered with an all-new, smooth shifting seven-speed manual transmission with Active Rev Matching.  It incorporates rev-matching technology for upshifts and downshifts.  This driver-selectable feature can be easily engaged or disengaged via paddle shifters on the steering wheel.  The seven-speed is used with a new dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia.  The transmission with the Z51 Performance Package includes specific close-ratio gearing for more aggressive driving.  This system anticipates the next gear selection and electronically ‘blips’ the throttle to match engine speed for a seamless gear change.  A six-speed automatic with paddle shifters is also offered.  It is optimized for use with Active Fuel Management and features a lower-inertia torque converter for improved shift quality and shift speeds.  In addition, shift feel and shift points can be adjusted through the Driver Mode Selector to give me another thrill when driving with an automatic instead of the manual.  The Corvette retains its distinctive rear transaxle layout for optimal weight balance.
