If the Series III is a bit slow ...

Not sure why any follower of 4wdNewz would want one but, just in case, the 2012 Jeep Grand Cherokee SRT8 has made its debut at the 2011 New York Auto Show. It'll be here next year, Said to be the fastest Jeep ever built, it knocks off the 0-100 run in under five seconds and tops out at a governed 250km/h. It'll run the quarter mile in the mid-13-second range, pull .90g on the skid pad and stop from 100km/h in under 33m. All this and Jeep reckons the 6.4 litre 350kW Hemi gets 13 per cent better fuel economy than its predecessor thanks in part to an active exhaust system that lets the cylinder-deactivating technology work over a wider rev band.
