The locomotive of the new Bentley Turbo RT produces 400 bhp, doing best possible than that of its predecessor, the Turbo R. The model has trusted pushrod 6.75L V8, which offer all alloy construction, Zytec fuel injection, a 5-bearing forged-steel crankshaft and a Garrett AirResearch turbocharger to generate 400-hp.

It has a four speed transmission system. The maximum torque of 553 lb.ft. yield a sensation in one motoring journal as "a tidal wave of uninterrupted power". But the maximum torque of the Bentley Turbo RT, attained between 2000 and3450 rpm.

The sensation of driving a Turbo Rt to the person behind the wheel is outside the normal frame of reference. There are large reserves of good, instant, manageable might, at any speeding from 15 mph to most 10 times that figure.

With the Turbo RT, the over-riding sense, from idling upper through to the red line, is of relentless power; of the can campaigning into one's backward accompanied by the large, muted growl of the locomotive.
