Quaife R4 GTS drawing 1998 silver GT

A forgotten British supercar which made its debut at the Birmingham Motor Show in 1998.
Before talking about this radical Lotus Elise GT1 alternative, I would briefly like to introduce
the company that made this beast.

R.T. Quaife Engineering, Ltd. is a British manufacturer of automotive drivetrain products. It designs and
manufactures replacement gearboxes and gear sets, some of which are for four-wheel drive systems
From a 6.0L V8, this beast produced an outstanding 600 bhp, what's more, it also had 4WD, something which many
supercars of that era did not possess. But as this was only a prototype, it's unclear as to whether this engine
functions or not.
Quaife's signature product is its line of automatic torque biasing differentials, a form of limited slip
differentials (LSD) that employ helical gears rather than clutch mechanisms that are controlled either
mechanically or by computers. These differentials are usually available as aftermarket items, but for
some models are specified by automobile manufacturers as OEM equipment.
Quaife has also briefly built complete road cars, with the R4 GTS in 1999 which also competed in the
British GT Championship. The company has also produced the R40, a roadster with a rear mounted V8
bike engine mated to one of the companies transaxle gearboxes. The 40 relates to the 40 valves the engine has.

All done in pen and took 3 hours to do. Rear view detail study.
