Suburban Terror: Hennessey offers upgrade packages for GMC SUVs

Lest you think that Hennessey Performance Engineering will only tune up your Dodge Viper or Cadillac CTS-V, feast your eyes on this little number showing one of the company's souped-up SUVs taking on a 2011 Nissan GT-R. It's really an unfair fight: The Cadillac Escalade sports a 6.2-liter V8 which in stock form makes about 400 hp. But Hennessey, not looking for a beatdown, drops a twin-turbocharged 427 cubic-inch LSX engine with high-flow cylinder heads, intake and exhaust upgrades, a performance camshaft and a laundry list of other parts to bring the truck's output to 1,000 hp.

Renault Twin’Z Concept previews 2014 Renault Twingo

The Renault Twin’Z Concept, designed by British designer Ross Lovegrove, is an electric city car previewing the 2014 Renault Twingo. The Renault Twin’Z Concept is a small, just 3623mm long, urban runaround with a small electric motor good for 67bhp and 167lb/ft of torque  and weighing in at 980kg, complete with a fairly sophisticated double wishbone suspension and relatively long wheelbase with a wheel at each corner stance. The Twin’Z is very much a concept car - designed by British designer Ross Lovegrove – and comes complete with the usual concept fripperies like electric suicide doors, cameras instead of rear view mirrors, sweeping LED lights, a solid crystal rear spoiler and big, complicated alloys.

McLaren 650s Configurator goes live

The McLaren 650S Configurator The new McLaren 650S arrived at the Geneva Motor Show last week – and as the 650S Spider too – and looks, and performs, far better than the 12C. That seems to point to the McLaren 12C being allowed to whither on the vine as McLaren’s customers opt for the new 650S instead of the 12C – even with a price difference heading towards £20k – although officially you can still buy a 12C (although we hear 12C production has been halted). We hear McLaren have already built a number of 650S models and now they’ve even got the 650S Configurator up on their website so customers – and dreamers – can spec up their new 650S.
