Power and torque figures for the new Chevrolet Corvette Stingray have been officially announced, revealing the highest standard power ratings ever for the US muscle car.

Powered by the all-new 6.2-litre LT1 V8 engine, the Chevrolet Corvette Stingray has been officially rated as having 339kW of power and 624Nm of torque with the standard exhaust system fitted but as much as 343kW and 630Nm with its optional performance exhaust installed.

The figures – equating to around 55kW per litre – are not only the highest ever for a standard Corvette, Chevrolet claims they come with greater efficiency too, with the Corvette Stingray expected to better 9.1 litres per 100km for highway driving.

With 428Nm available at only 1000rpm, and 90 per cent of peak torque available from 3000rpm to 5500rpm, Chevrolet estimates the Corvette will complete the 0-100km/h sprint in less than four seconds.

Chevrolet small block chief engineer Jordan Lee said drivers would experience more power and acceleration than ever before with the standard engine.

“Its power and torque surpass many up-level engines offered by competitors,” Lee said.

The small block engine features a string of new technologies including direct injection, continuously variable valve timing, and cylinder deactivation management, along with an advanced oiling system with oil-spray piston cooling, an optional dry-sump oiling system, and high-flow, four-into-one exhaust manifolds based on the design of the C6 Corvette Z06’s racing-derived 7.0-litre LS7 engine.

While the new seventh-generation Corvette may be the most powerful yet, it still loses the numbers game to its natural rival, the 477kW/814Nm 8.4-litre V10-powered SRT Viper GTS.

The 2014 Chevrolet Corvette Stingray coupe goes on sale in the US in September, with the Chevrolet Corvette Stingray convertible to follow later in the year.

    Wait till the tuners get a hands on this, with the LS7 we got 380rwkw with exhaust and tune….

    With 450Nm at only 1000rpm, this is going to make the series 2 Gen F HSVs very fast indeed when it replaces the LS3.

      Imagine what they will do with a series 2 GTS!

        I think you’ll find the LSA remains in the GTS unchanged as it will still out-power the LT1.

    And that’s just the base model. LS9 is still to come.

    Nice! Very nice.

  • Hung Low

    Very impressive specs no matter what the econo clowns and euro snobs have to say and as mentioned, the potential is huge.

    Since when did the base model corvette compete with the Viper? I’m sorry that is just a poor throw away line at the end.
