Car owner Richard Holt made the 250.1-mph run in late March, but video was posted just this week.

Jaguar XJ_e PHEV Plug-in Hybrid wins RAC Awards

The Jaguar XJ_e PHEV plug-in hybrid has won the RAC ‘Most Energy Efficient Luxury Car Prototype’ and ‘Technical Panel’s Award of Merit’. This year, Jaguar rolled out its experimental hybrid XJ – the Jaguar XJ_e, which we saw at this year’s Goodwood Festival of Speed – which managed to win the award for ‘Most Energy Efficient Luxury Car Prototype’ and also grabbed the Technical Panel’s ‘Award of Merit’ for its clever tech and frugal transit. Jaguar entered three XJ_e PHEV experimental cars in to the FCC, which managed to do the Brighton to London run on just 1.2 litres of petrol and 11kWh of electricity which adds up to an mpg of around 125mpg.

Concept Car of the Week: Oldsmobile Aerotech (1987)

In late 1984, Oldsmobile management had so much confidence in the potential of its new inline four-cylinder engine Quad 4, that a small team was assigned to the creation of the Aerotech, a research vehicle designed to demonstrate the engine's performance by setting a new world speed record. Ed Welburn, then assistant chief designer, was mostly working on the 1988 Cutlass Supreme but his passion for race cars made him the ideal candidate to be handed the assignment by Oldsmobile 2 studio's chief David North. Inspired by Le Mans racers such as the Porsche 917LH and Jim Hall's Chaparrals, he designed a long, flowing car that immediately seduced design director Chuck Jordan and GM management.
