A RACING CAR WEDGE

ALTHOUGH not allowed to race under Formula One regulations another new shape in racing cars is the wedge and what is more it is driven by a gas-turbine engine. It is the Lotus STP four-wheel-drive turbocar, powered by a Pratt and Whitney 674 gas-turbine engine rated at 610 h.p. The engine drives, through a reduction gearbox, two propeller shafts which in turn drive all four wheels. The exhaust outlet is a funnel behind the driver's cockpit. Top speed on the straight, 200 m.p.h. The wedge shape idea was to create an undisturbed flow of air to the gas-turbine engine. The driver is practically sitting on the floor; there are only two foot pedals - acceleration and brake. The car is only 2 ft. 10 ins, high. Length 14 ft. 2 ins. Width 6 ft. 3 ins. Wheelbase 8 ft. 6 ins. Weight 7 cwt.

KEY TO NUMBERED PARTS (1) Wedge shaped front. (2) Accelerator and brake pedals. (3) Air cooled disc brakes. (4) Differential drive to front wheels. (5) Front suspension system. (6) Cockpit instrument board. A "killer" switch on the steering wheel cuts out power and everything. (7) Air intakes, each side to rear of engine. (8) Steering arms. (9) Forward propeller shaft. (10) Reduction gearbox drive from engine. (11) Bag type side fuel tanks. (12) Air cooled disc brakes and rear suspen- sion system. (13) Differential drive to rear wheels. (14) Turbine wheel casing and engine drive shaft to reduction gearbox. (15) Pratt and Whitney 674 gas-turbine engine. Air enters at the rear, is compressed, mixed with fuel and ignited. The expanding hot gases drive the turbine wheel. (16) Exhaust outlet.
