Details and pictures of the new Lexus IS saloon have been revealed ahead of the car's full debut next week in Detroit. Previewed back in September at the Paris motor show with the LF-CC concept, the IS features the carmaker's signature spindle grille and L-shaped Daytime Running Lights (DRL). The IS also retains the prominent character line that rises from the lower body into the rear lamp clusters and also features another that runs underneath the windows.

Pagani Huayra sets Top Gear lap record and places marker for McLaren P1

The Pagani Huyra set a stunning record time on the Top Gear track last week and in the process laid down a marker for the new McLaren P1. The return of Top Gear at the weekend for Series 19 saw Richard Hammond get to grips with the Pagani Huayra – successor to his beloved Zonda – and after a thoroughly positive test drive Hammond handed over to the Stig to take the Huayra round the Top Gear track. In the hands of the Stig, the 6.0 litre V12 AMG engine with 730 horses powered the Huayra to a time of just 1:13.8, beating the previous record for a production car, held by the Ariel Atom V8, by a sizeable 1.3 seconds.
