The Caparo T1 is a British mid-engine, rear-wheel drive, two-seat automobile built
by Caparo Vehicle Technologies, founded by design director Ben Scott-Geddes and engineering
director Graham Halstead, engineers formerly involved in the development of the McLaren
F1. The T1 was inspired by Formula One design, and intended as a relatively affordable
street legal race car. The T1 was scheduled for production in mid-2007 for a price
of GB£235,000 (approx. US$480,000 or €328,000, c.2007), with approximately 25 cars
per year built.
The T1 has a dry weight of 470 kilograms (1,000 lb), an overall length of 4,066 millimetres
(160.1 in), an overall width of 1,990 millimetres (78 in), an overall height of 1,076
millimetres (42.4 in), and a wheelbase of 2,900 millimetres (110 in). It has a fuel
tank capacity of 55 litres (15 U.S. gal).
The T1 sports a 116-kilogram (260 lb), 32-valve, 3,496-cubic centimetre (3.5 L),
all-aluminium, naturally-aspirated, Menard V8 engine with cylinder banks mounted
at 90° and lubricated via a dry sump oil system. The design of the engine has gone
through several designs, previously including a smaller 2.4-litre supercharged unit.
The production design generates a maximum power of 575 horsepower (429 kW; 583 PS)
at 10,500 revolutions per minute and a maximum torque of 310 pound-feet (420 N·m)
at 9,000 revolutions per minute, giving the car a power-to-weight ratio of 1,045
horsepower per tonne (779.3 kW/t). In addition, the engine has been reported to successfully
reach 700 horsepower (520 kW; 710 PS) of power on methanol fuel. The engine is controlled
via a fully tunable Pectel SQ6 engine control unit and the throttle is controlled
via a throttle-by-wire system.
The T1’s gearbox is a 6-speed sequential made of a magnesium and carbon construction
that has a variety of available gear ratios and utilizes a pneumatic actuator to
shift, able to upshift in 60 milliseconds and downshift in 30 milliseconds. Furthermore,
the drivetrain incorporates a limited slip differential and equal length hollow tripod
The T1 has an estimated maximum speed of 205 miles per hour (330 km/h) on a low downforce
setup. From a standing start, it has an estimated 0–100 kilometres per hour (0–62
mph) time under 2.5 seconds and onto 160 kilometres per hour (99 mph) in 4.9 seconds,
depending on tyre setup. It is also capable of an estimated lateral acceleration
of up to 3 g and braking deceleration of 3 g, depending on tire setup. It also has
roughly twice as much horsepower per ton as the Bugatti Veyron.
