Mercedes confirms electric AMG SLS

By Richard Webber First Official Pictures 17 July 2009 09:46 Mercedes’ new AMG SLS – the gullwinged  GT supercar due to appear at the 2009 Frankfurt motor show – is going electric as engineers develop an emissions-free battery powered SLS as an alternative to the 563bhp V8. The eco SLS will have an electric motor powering each wheel, producing a total of 526bhp. Needless to say, for now it remains an engineering prototype – but a spokeswoman told CAR that Mercedes was intent on putting it into production.

McLaren P1 (2013) CAR's race-speed Goodwood ride

The McLaren P1 leaves the startline like a shard of shrapnel riding the percussion wave of an explosion. It needs high-definition slow-mo to describe it, like those films of a bullet shattering an apple, or the slow-motion shots of an F1 car skipping over a kerb, front wing flexing, tyres deflecting, all that physics captured in beautiful, drowsy detail. In my mind, when I re-live the first moments of my ride up the Goodwood hillclimb in McLaren’s new hypercar, I see the release of energy in the same 1500-frames-per-second style.

New Rolls Royce Wraith on the road (video)

The new Rolls Royce Wraith hits the road The new Rolls Royce Wraith – revealed at the Geneva Motor Show in March – is Rolls Royce’s answer to the sport credentials of Bentley, and it’s a convincing effort. Essentially a Ghost Coupe, the Wraith’s styling is, perhaps, a little jarring with its almost dog humping back end, but from some angles it also looks remarkably elegant for a two door coupe that’s the size of a delivery truck. But the key to the Wraith’s appeal – apart from the sumptuous fixtures and fittings – is its dynamism and power, with 624bhp on tap from its v12 (and an earth-turning 590lb/ft of torque too) enough to shift the Wraith to 60mph in a very un-Rolls Royce 4.4 seconds.
