Nobody likes to wait – especially for one of the most highly anticipated all-new sports cars on the planet… Simply the world waited v years for the details.
It was back in 2008 when rumours about a future all-new C7 Corvette starting time started swirling. However, it wasn't until early 2012 when the first heavily cloaked exam mules were spotted in the wild. Just even with concrete prototypes running in the public eye, Chevy was able to keep its upcoming flagship under impressively tight wrap. Finally, at the 2013 Detroit Auto Bear witness in January of this year, the automaker officially lifted the covers off the 2014 Chevrolet C7 Corvette Stingray and revealed its inner workings… Then everyone waited half-a-twelvemonth to bulldoze it.
Nevertheless all of that pent-up frustration, mental anguish and years of misguided speculation immediately vanished this week when I climbed behind the wheel and laid two fat strips of molten rubber down on the cobblestone. The disturbing was and so worth it.
At that place is no demand to embellish or sugar coat its past. The Corvette, America'due south iconic sports auto for the past lx years, has e'er fallen short of perfection. While belatedly model versions have generated enough of horsepower and delivered impressive cornering grip, the Corvette as a complete sports automobile package – styling, performance and passenger appointments every bit weighed – has never left enthusiasts speechlessly impressed. That is, until at present.
Merely before I get ahead of myself with driving impressions, permit'due south take a cursory refresher course on the all-new seventh-generation C7. (For an excellent in-depth expect, check out "2014 Chevrolet Corvette C7 Stingray: Everything In that location is to Know" that nosotros published earlier this year.)
Similar its ancestors, and despite countless rumours of a mid-engine successor, the new 2014 Corvette continues to employ a front-engine, rear-wheel bulldoze compages. Merely in contrast to its predecessors, the all-new model has abased much of its heavy steel construction in favour of a lightweight aluminum frame. Thank you to innovative build techniques, including plenty of structural adhesive bonding, the new chassis is 40 kg (99 pounds) lighter than last twelvemonth'due south model and 57 per cent stiffer. Continuing that trend, there are new featherweight torso panels, including a standard carbon-fibre hood and carbon-nano composite underbody panels, which assist in keeping weight to a minimum. The new bodywork is sleek (Cd of simply .29), fashionable, distinctive and light, boasting a curb weight of just ane,495 kg (3,298 pounds).
The Corvette's 8-cylinder tradition continues, just with an all-new, and thoroughly mod, naturally aspirated 6.2-litre V8. The all-aluminum LS1 pocket-sized block features direct injection and continuously variable valve timing to generate 450 horsepower and 450 pound-feet of torque. Equally such, it is potent enough to exist called the most powerful standard engine Chevrolet has ever offered on a Corvette.
Thankfully, and despite the recent trend of dropping manual transmissions, Corvette buyers are again offered the pick of whether or not to row their own gears. Gone is terminal yr's six-speed gearbox, replaced past a new seven-speed transmission gearbox (Tremec TR6070) with Active Rev Matching (ARM) every bit standard equipment. Those who cull merely two pedals in the footwell will receive a carryover 6-speed automatic (Hydra-Matic 6L80) with standard wheel-mounted paddle shifters. In both cases, the gearbox is incorporated into a rear transaxle that helps to improve overall vehicle balance, and models equipped with the optional Z51 Performance packet besides receive a three-mode electronic express-skid differential.
The suspension has also been significantly overhauled. Even though the short/long-arm configuration returns, its componentry is all new with hollow lower control arms and new aluminum rear tow links that combined salvage well-nigh eleven pounds compared to the previous pattern. Standard models arrive with 35-millimeter piston Bilstein monotube shocks, while the aforementioned Z51 upgrade includes 45-mm dampers. GM'due south third-generation Magnetic Ride Control (MRC), now reportedly reacting 40 per cent quicker than its predecessor, is offered as an choice.
Power steering is at present electric to save weight, improve packaging and increase fuel economy, and the system provides variable endeavor and different ratios based on driving weather condition. Chevy increased steering column stiffness past 150 per cent, and torsional stiffness by 600 per cent, which makes the system five times more rigid than its predecessor. Overall, the new steering was engineered to provide greater on-center sensitivity, more linearity and better feedback during high-performance driving.
The standard wheels are staggered bandage aluminum measuring 18 x 8.5 inches front and 19 ten x inches rear, wrapped in new Michelin Pilot Super Sport run-flat tires (245/40R18 and 285/35R19) designed specifically for the Corvette. Models with the Z51 package volition wear even larger forged aluminum wheels (19 x 8.5 inches front end and 20 x 10 inches rear). The tire width is the same, only the sidewalls are shorter and the dual-compound rubber is more ambitious. Fifty-fifty though some volition annotation the tire width is narrower than many of last year's models, Chevy claims the reduced footprint improves steering response and fuel economy while still delivering more than 1g in cornering forces.
Braking is accomplished through standard Brembo brakes, with four-piston fixed calipers at each corner. Front rotors are 320 mm (12.half dozen inches) in diameter, while the rear rotors are 338 mm (13.3 inches) in diameter. The new organization offers 35 per cent more than swept area, and Chevy says stopping distances are improved past nine per cent. All Z51 models volition feature slotted rotors with larger diameters front and rear (345 mm and 338 mm, respectively), and brake ducts to improve cooling under severe use.
Mechanically speaking, the new C7 looks impressive on paper – simply and then did its predecessor. Equally most volition adjure, the Corvette's Achilles' heel has always been its lackluster interior. Only to its credit, Chevy has addressed this as well.
All models of the new C7 feature an interior devoid of the hard plastic surfaces that sabotaged its forebears. While information technology nonetheless won't keep the craftsmen at Rolls-Royce upwards at night, everything within the C7 Corvette'due south motel is now covered in premium materials, whether they are rubberized, wrapped in Napa leather or molded in genuine carbon fibre. The seats, an frequently-mentioned embarrassment in the past, accept also been redesigned. Buyers may opt for either a standard GT bucket, or a Competition Sport seat (late availability). Both are constructed with a lightweight magnesium frame to meliorate rigidity and decrease weight.
Rather than write another 5,000 words, and only cover a sliver of what's new with the C7, this infinite is better utilized discussing what really matters – the Corvette'south driving dynamics.
Presented with nearly a dozen sparkling make clean examples in a large parking lot, all with unique transmissions and options, I bolted towards a Z51-equipped model (tip: look for its total-width rear spoiler) with a 7-speed transmission manual and MRC suspension.
Later a quick walk-effectually to inspect and admire the new styling (sharp, edgy and distinctive) and take in its size (the new Corvette is nearly identical to the size of a Porsche 911, but larger than the SRT Viper), I opened the servo-operated door and dropped into the 2-place cockpit. My half-dozen-human foot 2-inch frame felt snug, so I moved the power-operated seat rearward to its full stop. With my legs comfortably extended, I had about an inch or 2 of headroom and my thighs and back were firmly supported by the new GT seats. In terms of condolement and bolstering, they are a total 2 letter of the alphabet grades improve than the chairs they replace. What an improvement.
The all-new cockpit is every chip equally pleasing as the new seats, fifty-fifty in base configuration. I scanned every visible surface and was unable to find any "old GM" carryover components. The new steering wheel, slightly smaller in diameter, is thick and felt great in my hands. I also noticed in that location are paddle shifters on all models, regardless of manual pick (more on that in a moment).
A printing of the square get-go/stop button to the right of the steering wheel fired the V8 up instantly. The instrument cluster went through its light prove and needle dance, and the engine settled to a tranquillity idle. By default, the exhaust note was muted and timid. That was to be easily changed.
Chevy has gone to great lengths to ensure its new Corvette is commuter-focused, and a large office of its endeavour went into the new Commuter Style Selector. This cockpit-mounted rotary knob, located just aft of the transmission shifter, allows the operator to choose betwixt five unlike pre-configured settings – weather, eco, touring, sport and track – that alter 12 dissimilar performance parameters, things similar throttle response, the guess cluster brandish, steering effort, traction command, active fuel direction, etc. Each completely change the personality of the new C7.
I toggled out of touring, the standard start-up style, and selected sport. The tachometer graphics reconfigured, and the four-cannon audio rails from the center-mounted frazzle in the rear immediately became more than menacing.
The new seven-speed manual transmission has a mechanical feel, tacitly reassuring in a skilful way, with a clutch that only grabs during the last couple inches of travel. It took some getting used to its detail launch preferences (I'll admit to stalling the C7 more than once), but underway it was silky smooth. As mentioned, Active Rev Matching is standard on the 7MT versions. The wheel-mounted paddles, which are used to select gears on the 6AT cars, are tasked with switching the ARM organization on and off with transmission gearboxes (the digital gear indicator on the instrument console goes from white to xanthous when ARM is active). Unlike similar systems from other automakers, which must wait until the gear is fully selected, the GM organization uses advanced sensors to predict the next gear. In practice, information technology works much ameliorate than whatever other system that I have interacted with.
Don't try to deny the power under the vented front hood. Pound the accelerator pedal and the new C7 Stingray launches violently off the line – there is naught unimposing almost information technology. Chevy is challenge 0-lx mph (96 km/h) happens in 3.viii seconds with a quarter mile accomplished in 12.0 seconds at 119 mph (191 km/h). In real-world driving, it felt every bit that quick, with a delicious V8 soundtrack to accompany the head-snapping acceleration forces. Burnouts were a no-brainer (traction and stability control may exist completely defeated), but the sticky Michelin tire compound didn't produce clouds of centre-candy white smoke. Mayhap it was the asphalt surface?
Chevy is really proud that its Corvette earns 8.1L/100km (29 miles per gallon) on the highway wheel. It accomplishes this through an annoyingly alpine 7th gear and Active Fuel Direction (the 450-hp V8 literally becomes a 126-hp V4 during steady-state cruising under certain weather condition). During one highway segment, I brought the Stingray to 60 mph (96 km/h) and put it into its tallest gear. Then I floored information technology. The acceleration was ane click higher up not-existent, meaning it took about 10 seconds by my wristwatch to hit 70 mph (112 km/h) – I am betting the Chevrolet Cruze Eco can shell information technology in this configuration. Sixth gear is just marginally better, so I spent my three hours behind the wheel but using first through fifth gear. Of class, I wasn't paying for fuel.
The C7 is very stable at speeds far to a higher place those posted on regime-issued reflective roadside signs, but I found it equally competent in the twisty sections. Tire grip was excellent, and the MRC (nonetheless my personal favorite among the active systems on the market place) was unflappable. The new chassis drives with a very light feel – you will be surprised – with quick transitions easily provoked through the nicely weighted steering. Braking was a potent bespeak as well. If asked to grade the Stingray, information technology earned directly Every bit in the major functioning categories (acceleration, braking, cornering and high speed stability).
But I was less impressed with the automatic model, which I drove afterwards in the twenty-four hour period, that lacked the Z51 and MRC options. The traditional half dozen-speed automatic seemed to extinguish the C7'southward performance edge. I found it softer, slower and more lethargic (even paddle-initiated shifts had annoying lag). Fifty-fifty though it was every bit as quick in terms of outright acceleration, the gearbox took much of the excitement out of the driving feel. Don't place your bets on my long-term theories, merely I am speculating that a time to come Z06 model volition introduce a proper dual-clutch automated gearbox that will put the tired slushbox to pasture.
To simulate a track experience, Chevrolet coned-off a large skidpad at a local airport and allowed journalists to run endless laps in 7MT models equipped with the Z51 and MRC options. With Bulldoze Select in track style, the Stingray was impressively competent with a well-counterbalanced chassis that was like shooting fish in a barrel to place right on the base of each orangish mark. Braking was stiff, and pedal modulation was expert. Mid-corner balance was excellent, just I did note moderate understeer when braking late into several tight corners – this was unexpected, and it actually slowed me down. We cannot wait to run it on a proper rails to explore its handling farther.
As far as disappointments go, the C7'southward list is rather short. The new Commuter Manner Selector is brilliant in design, simply the electronics seemed slow to transition between settings and its click-past-click toggle fabricated it hard to get the proper mode downward on the get-go effort (why not apply a pocket-sized cycle interface with physical detents as each style is passed?). The stylish exterior mirrors look cool, but they are too small to provide a comfortable view to the rear and sides of the sports motorcar. I also constitute that the tinted acrylic roof panel (ane of three available choices) immune too much rut into the cabin, causing the climate control system to work much harder compared to the opaque options. Lastly, I'd like two or iii quick sequential presses on the door release to open the door, regardless of lock setting (having to hunt for the unlock switch each time makes exiting the Stingray a multi-step process).
Overall, I was really impressed by the all-new C7 – it is the best Corvette I take ever driven.
But the elephant in the room remains obvious comparisons to the SRT Viper and Porsche 911. Lacking the 3 cars to bulldoze dorsum-to-dorsum only having driven all iii separately, my have is that the Viper remains the most engaging, exciting and visceral of the three. Despite SRT'southward endeavor to tame it, it is an exotic that has a raw border purposely engineered to increase centre rates when its V10 roars to life. The Porsche 911 remains the gentleman of the pack, with the best build quality and a rear-mounted apartment-six demeanor that gives upwardly some overall performance in substitution for impressive refinement, poise and class.
As per yesterday'southward article, the highly anticipated 2014 Chevrolet Corvette Stingray coupe volition have a suggested starting retail price of just $52,745 in Canada, with the 2014 Corvette Stingray Convertible starting at $58,245. The Z51 Performance Package on the 1LT trim starts at $56,520 and the Z51 3LT trim starts at $64,975 for those of yous seeking the ultimate in Corvette operation. (Prices for all 2013 Corvette models excludes $1,700 destination fee, taxes, title, and license fees).
The all-new C7 Stingray emerges equally the about versatile sports car of the trio, and a technological masterpiece. It is a performance bargain – by a large margin – and it offers the best balance between daily commuter civility and track-fix capability. Different each of its half dozen predecessors, which accept always seemed to autumn brusk of a complete package, Chevy has finally delivered a Corvette that raises the bar without whatever excuses.
