New Corvette. Mid-engined! Right-hand drive!

Chevrolet’s long-running Corvette is reinvented as a mid-engined junior supercar, and it’s coming to the UK in right-hand drive. By

America’s sports car becomes a global challenger with the imminent arrival of the C8 version of the Corvette: still powered by a pushrod V8, still fibreglass bodied, but now mid-engined and ready to rival high-performanc­e European two-seaters. And for the first time, Corvettes will be built at the Kentucky factory with right-hand drive.

Born in 1953 as America’s MG TF, Corvette’s once tawdry reputation, based on poor build quality and boorish manners, is ancient history. Fending off import and domestic challenger­s – Ford’s Thunderbir­d, Dodge’s Viper, every Porsche – has been the Corvette’s cause for ages. But now it goes up a division, as the 2020 model will be the long-rumoured mid-engined edition.

Corvette patron saint Zora Arkus-Duntov – not the car’s creator, but its champion within GM for two decades – figured that the

engine needed to be moved behind the driver when his Corvette SS racer parboiled driver John Fitch’s feet at the 1957 12 Hours of Sebring. Why did it take GM so long? Blame company politics, conservati­ve shareholde­rs and GM’s 2009 bankruptcy as the key roadblocks.

Peeling off the camouflage in July, GM president Mark Reuss said: ‘What necessitat­ed this upheaval was the fact that the traditiona­l front-engined Corvette had reached its performanc­e limit. The new mid-engined car looks and feels like a Corvette but now drives better than any of its predecesso­rs.’ In other words, adding power up front accelerate­d nothing but the conversion of rear tyre rubber to white smoke.

Mike Simcoe, vice president of design, called the 2020 model ‘a historic opportunit­y sought for over 60 years. Our new sports car ⊲

is not only the best of America, it will stand tall against the best the world has to offer.’ Executive chief engineer Tadge Juechter, the main modern-day mid-engine proponent, described his mission as ‘blending traditiona­l Corvette attributes with a supercar’s performanc­e and driving experience.’

Key components carried over from the C7 include aluminium spaceframe chassis constructi­on, now 10 per cent stiffer, fibreglass body panels, a pushrod V8 engine, Brembo brakes, and cast- or forged-aluminium suspension members. A choice of Michelin Pilot ALS (all season) or 4S (summer only) tyres will be offered in 19-inch front and 20-inch rear sizes.

With an optional performanc­e exhaust system, it delivers an impressive 495bhp at 6450rpm and 470lb ft of torque at 5150rpm, the highest output ever offered in a base Corvette. That’s a notable achievemen­t for a lowly 16-valve pushrod V8 whose lineage dates to 1955. This fifth-generation small-block engine has aluminium block and head constructi­on, 11.5:1 compressio­n, direct fuel injection with cylinder deactivati­on under low load, dry-sump lubricatio­n, and variable valve timing.

The only transmissi­on offered is an eight-speed paddleshif­t dual-clutch automatic supplied by Tremec. There’s no gearlever; instead, two toggles and three push buttons on the centre console select the direction of travel and the shift mode.

The C8 is longer and wider, with wider tracks, but it’s fractional­ly lower. It’s also heavier than today’s 1496kg C7, but, Juechter claims this will be the best accelerati­ng Corvette ever offered thanks to the extra weight over the rear tyres (the front/rear distributi­on has not been revealed). He adds that cars equipped with the optional Z51 performanc­e package, which includes low-restrictio­n exhaust and a higher axle ratio, will easily duck below three seconds in the rush from rest to 60mph.

According to Juechter, the toughest engineerin­g challenge was keeping the Corvette cool in the hands of a profession­al test driver on 40ºC days. ‘We have three radiators – two in front, one fed by the left-side air scoop. Unfortunat­ely, the cooling air that enters the rear of the car sweeps over hot exhaust headers before smacking into our huge trunk compartmen­t. To aid the exit of that flow, we have electric fans in the rear corners of the car and an open slot at the bottom of the hatch glass. The new gearbox adds major cooling needs. We addressed that concern by incorporat­ing a transmissi­on-fluid-to-coolant heat exchanger mounted atop the transaxle.’

There will be no overlap between C7 and C8 generation­s; the last C7 machines will be built at the end of September. Thus far, GM has revealed no delivery details beyond stating that C8 production will start later this year. If the C8 drives well, it could follow the Ford Mustang in being an enduring US icon that goes truly global – helped by a price (£80k, we’re hoping/ guessing) that makes its performanc­e accessible to those whose budgets won’t stretch to an Aston Martin, Ferrari, Lamborghin­i or McLaren.

A CORVETTE FOR THE UK

Yes, you read that right. We asked GM Europe, and they told CAR: ‘We can confirm that the next generation Chevrolet Corvette will be built as a righthand-drive variant and will o cially be sold in the UK. This is a milestone for us, with the UK being one of the most important sports car markets in the world.’ But at the moment GM is not o ering any details on UK price, timing, spec or distributi­on channels. The challenge there is that since GM sold Vauxhall/ Opel to PSA, GM in Europe has been little more than a maker of diesel engines, so there’s no establishe­d dealer network through which to sell the Corvette.
