The Caparo T1 is Beautifully Engineered

”To demonstrate our understanding of these fundamental vehicle engineering issues we set out to design an optimum package for delivering 1,000bhp-per-tonne,” says Caparo co-founder Ben Scott-Geddes. ”Interestingly, the sweet spot on the curve that satisfies many of these issues is 500 horsepower in a vehicle with a mass of 500kg.”

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 exterior of the T1 closely resembles that of a racing prototype or Formula One racing car. It features a carbon fibre aerodynamic low drag body design, composed of individual sections, with an adjustable twin element front wing, single element rear wing, and fowler flaps, and a ground effect diffuser, allowing it to create 875 kilograms (1,930 lb) of downforce at 240 kilometres per hour (150 mph). The wings are replaceable with road and track variations.

The chassis of the T1 is composed of a carbon fibre and aluminium honeycomb monocoque with a front composite crash structure and a rear tubular space frame construction. The suspension is of a double wishbone design with tunable anti-roll bars, front and rear, and five-way adjustable race dampers. The braking system is composed of 355-millimetre (14.0 in) steel brake discs, with six-piston and four-piston callipers front and rear, respectively. The brake bias pedal box is fully adjustable and brake pads are available in various compounds.

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 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 1,223 horsepower per tonne (912.8 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 driveshafts.

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.
