Supercharged LSA-Powered Commodore Heads To U.K., Is The U.S. Next?

Follow Viknesh

You’re looking at the latest flagship from Holden tuner HSV, the 2013 GTS super sedan, which is based on the Australian VF-series Holden Commodore that’s due to go on sale later this year in U.S. showrooms as the 2014 Chevrolet SS.

The GTS, which packs a supercharged 6.2-liter LSA V-8 engine, has just been confirmed for sale in the U.K., where it will wear Vauxhall badges, and with any luck we’ll see the car, or something like it, in the U.S.

Performance fans will recognize the GTS’ engine as being the same unit fitted to cars like the outgoing Cadillac CTS-V and Chevrolet Camaro ZL1. In the GTS, the engine has been tuned to deliver 580 horsepower and 545 pound-feet of torque.

For those at home counting, that’s more horsepower than in the Audi RS 6/RS 7, BMW M5 and Mercedes-Benz E63 AMG.

It’s entirely possible Chevrolet will launch more powerful versions of the SS (so far the car has only been announced with a LS3 6.2-liter V-8, rated at 415 horsepower and 415 pound-feet of torque) but any range-topping model is more likely to come from within General Motors than an outside firm such as HSV.

The good news is that the LSA powerplant is fully owned by GM and installed in the GTS sedan at the Holden factory where the donor Commodore is assembled. This means SS sedans packing the engine could be sourced direct from the factory.

The good news doesn’t end there, however. The GTS is available with a manual transmission in addition to a six-speed automatic. Other goodies include a launch control system (manual transmission only), electronic rear differential and a version of GM’s magnetic ride suspension with three different settings.

To assist drivers in manipulating the various performance systems, a new Driver Preference Dial is featured. Located behind the gear lever, the dial adjusts settings to one of four modes: Touring, Sport, Performance and Track. With this, the vehicle’s stability and traction control systems, launch control, bi-modal exhaust, rear differential and electronic power steering can all be adjusted.

The stock wheels measure 20 inches in diameter and are wrapped with Continental 255/35 (front) and 275/35 (rear) tires. Inside these are AP Racing brakes with six-piston, forged aluminum calipers.

We suggest you drop whatever it is you're doing and go out to your nearest Chevy dealer and start demanding an SS with similar spec.
