SEMA: Hennessey HPE750 Convertible

584kW and 878Nm – enough to blow off even the hardiest of toupees

SEMA Hennessey HPE750 Convertible

Famed Texan tuner Hennessey has unleashed a trio of modified monsters at SEMA 2015, and unbelievably this 584kW Mustang convertible is the least wild of the bunch.

Using the latest Ford Mustang GT Convertible as a base, Hennessey adds a 2.9-litre supercharger blowing 9psi (0.6bar) boost into the 5.0-litre Coyote V8.

Huge 384mm front rotors clamped by Brembo calipers front and rear bring it all to a halt, while Michelin Pilot Super Sport tyres attempt to put all that grunt to the ground, wrapped around the buyer's choice of 19- or 20-inch wheels.

What's not in doubt is its top speed of 335km/h, which was achieved on a recent episode of Jay Leno's Garage, at which speed the carbonfibre front splitter, side skirts and rear lip spoiler no doubt do their part in keeping this Mustang on terra firma.
