Wrangler works a muscly overhaul

Chrysler's in-house tuning car arm Mopar has worked its muscle car magic on the Jeep Wrangler.

It released sketches of two special editions it will launch this week at the annual Jeep Safari in Moab, Utah.

The black and gold emblazoned Renegade is a slightly higher riding Wrangler sporting a noticeably large bonnet bulge.

There aren't any details on the engines or performance figures just yet, but it's likely the extra space under the bonnet means Jeep has squeezed in a Hemi V8 engine. That would give the four-wheel-drive around 270kW.

Mopar's other Wrangler concept is named Pork Chop. It is a stripped down, lightweight buggy, with bright red racing bucket seats, a roll cage and chunky off-road tyres.
