New Vauxhall VXR8 GTS gets 576bhp & costs £54,999

The new Vauxhall VXR8 GTS gets 576bhp If you’re going to make your most potent saloon car more powerful, you could just tweak the engine management a bit to add a few more horses. But Vauxhall have gone a bit further with the latest VXR8 GTS – it gets a 6.2 litre V8 from the Camaro ZL1, a whole 150bhp and 140lb/ft of torque than the old VXR8. Vauxhall has based the GTS on Holden’s new GEN-F GTS – Australia’s maddest production Holden – and the increase in power comes courtesy of a supercharger, new exhaust system.

New Ford Focus ST is Europe’s best selling hot hatch.

The new Ford Focus ST has become the best selling hot hatch in Europe in the last three months, outselling the Golf GTi and Renault Megane Sport. But the new Focus ST finally went on sale last summer, and started arriving in Ford’s UK showrooms in the Autumn, as the ST finally hit Europe’s roads. At a starting price of £21,995, a more aggressive look and decent performance – 0-62mph in 6.5 seconds – the new Focus ST is an appealing performance bargain, even if 250 horses through the front wheels is a big ask.

Hyundai i20 WRC starts testing

Hyundai has been busy plotting its return to WRC Rallying for 2014, but so far it’s all been about behind the scenes work on building an i20 capable of taking on the rally world and gathering a team that can make it a success. But with the first official outing for the i20 due in January 2014 in Monte Carlo, Hyundai has finally taken their i20 WRC out in the world to give it some proper testing outside the workshop, Hyundai have been playing on a private testing ground to check out the i20′s systems, followed by a comprehensive testing session to work on different setups and gather data, with a major focus on the i20′s 1.6 litre turbo which, until now, hadn’t been run in the car outside Hyundai’s R&D. Hyundai say all went well over the 55okm of testing across three days, a prelude to a full programme of testing in the coming months as Hyundai get closer to their official debut.
