Hennessey has given the new Ford Bronco 405bhp

The internet’s hottest off-roader that’s not a Defender has already been given the Hennessey treatment. Welcome to the – deep breath – Hennessey VelociRaptor 400 Bronco.

Unsurprisingly, the 400 Bronco produces a smidge over 400 horsepower – 405bhp to be exact – which is 75bhp more than the current factory range-topper, the 2.7-litre twin-turbo V6 with 330bhp. Torque also rises by 88lb ft to a total of 503lb ft in Hennessey’s motor.

It’s been achieved via The Usual Suspects: an upgraded ECU and exhaust, and a high-flow air induction system. Hennessey reckons it’ll do 0-60mph in 4.9s, which isn’t too shabby at all.

The Hennessey Off-Road pack adds 35in off-road tyres on 18in wheels, new VelociRaptor bumpers front and rear, retractable side steps, some badges and even embroidered headrests.

Everything’s warranted for three years/36,000 miles, and it keeps all the original Bronco’s modes and off-road systems (which, as it turns out, are rather good). Hennessey’s only building 200 models this year, in either two/four-door and with our without a soft-top. The price? $24,950, on top of the small matter of buying a new Bronco.

“Whether you’re on- or off-road, more power is what our customers demand, and our VelociRaptor 400 Bronco really delivers,” explains boss John Hennessey.
