New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10. Most of the new A6 range has now arrived in showrooms – including the S6 and Avant – but what’s still missing is a new RS6, the Audi that used to have the heart of a Lamborghini. But as we reported in April, the 2013 RS6 is well on the way but it will be losing its Lamborghini V10 with its 5.2 litres and 572bhp and will instead get the Audi/Bentley twin-turbo 4.0 litre V8.

GM to modify Chevrolet Volts to guard against battery fire

General Motors will add a structural reinforcement and devices to prevent overfilling of the battery cooling system in the Chevrolet Volt hybrid sedan to prevent the possibility of a fire after a side crash. The changes come seven months after a Volt caught fire three weeks after being crash-tested by the National Highway Traffic Safety Administration. The government agency in November opened a defect investigation into the Volt because of the battery fire.

New Alfa Romeo Giulietta Quadrifoglio Verde gets Alfa 4C engine

The new Alfa Giulietta & MiTo Cloverleaf Heading for Geneva next week will be a pair of updated range-toppers from Alfa Romeo – the Alfa Giulietta Quadrifoglio Verde and MiTo Quadrifoglio Verde – with the Giulietta the more interesting of the two. The engine in the new Alfa 4C is based on the engine in the current Alfa Giulietta, but now Alfa has decided the old 1750 TB engine in the Giulietta should make way for its new, lighter sibling from the 4C so the Giulietta will come with the same 1750 Turbo Petrol developing 237bhp and good for a 6.6 seconds 0-62mph sprint. Other tweaks for the Giulietta Quadrifoglio Verde include big tail pipes, 320mm Brembos, new bodykit, 18″ alloys, sports seats, leather and Alcantar trim, new instruments and a black roof.
