Mercedes SLS AMG Black Series (2012) first pictures

We’d be most surprised if you rejected the Mercedes SLS AMG for being too slow and too subtle, but if you crave a few racecar touches for your gullwing supercar then Mercedes will oblige with this: the SLS AMG Black Series.

Read on for the full spec of a Mercedes with more power than a McLaren 12C Spider.

'Rat run' short cuts make journeys slower

DRIVERS taking "rat-run" short cuts could actually be making their journeys slower, according to a survey.

McLaren P1 gets 903bhp

McLaren has revealed that their new supercar – the McLaren P1 – will deliver 903bhp and have emissions below 200g/km. The McLaren P1 will get 727bhp from its 3.8 litre V8 with an additional 176bhp coming from an electric motor for a combined power delivery of 903bhp, with the V8 contributing 531lb/ft of torque and the electric motor an instant 192lb/ft for a combined torque of 664lb/ft at 4000rpm. The boost from the electric motor is instantly available at the flick of a button on the steering wheel – McLaren call it Instant Power Assist System (IPAS) – which instantly throws more additional power to aid the McLaren’s V8 than a pair of Fiestas can manage.
