Mercedes S63 gets new 5.5 litre V8

The Mercedes S63 AMG is the firts to get the new AMG 5.5 litre V8 Bi-Turbo Mercedes’ top end AMG engine has changed over the last few years. It’s gone from a 5.5 litre supercharged lump to the now ubiquitous 6.2 litre normally aspirated engine, which anomalously gets badged ’63′ throughout the cars that sit at the top of each of Mercedes big-engined ranges. But now we go back to the future with the return of a 5.5 litre V8 – admittedly a completely new engine (M571) – which this time round sports a pair of turbochargers and delivers 554 hp and 590lbs/ft of torque.

McLaren 650S Sprint revealed – debuts at Pebble Beach

The McLaren 650S Sprint arrives to hit the track The arrival of the McLaren 650S in February (and the end of the 12C, unless it’s being replaced by the McLaren 625C) meant, in all probability, that the various hardcore versions of the 12C would be replicated for the 650S. We’ve already has the new McLaren 650S GT3 at Goodwood this year, and now we get the car that fills the gap between the 650S and GT3 version for McLaren owners to take to the track – the McLaren 650S Sprint. The 650S Sprint – which we assume replaces the 12C Sprint – keeps the 650S’s 641bhp V8 but adds a hefty dose of track specific updates to make the Sprint more focused and with sharper responses.

Citroen AirCross – based on Citroen C3 Picasso – revealed

The Citroen AirCross - looks like a South America only crossover This could be a new car from Citroen, but it could just as easily be another of those oddities that car makers throw at the southern end of the Americas. Citroen in Brazil has revealed – via Twitter – the Citroen AirCross, which is basically a Citroen C3 Picasso with a bit of Crossover / SUV butchness thrown in to create a rugged urban crossover. And it’s based on the old Citroen C3, which makes us think there’s a chance this may not be a world car.
