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 tyre setup. When driving the Caparo, Jeremy Clarkson, presenter of the British car show Top Gear, had stated that limited aerodynamic downforce is created at slow speeds. As a result, the car had low levels of lateral traction while cornering if it was not being driven rapidly. Aerodynamically, this vehicle is designed such that air passing over the body at high rates of speed "pushes" the vehicle against the road (allowing for higher cornering speeds). Clarkson criticized the handling characteristics proposing that if the vehicle was better at negotiating corners and bends in the track at higher speeds than at lower speeds. On a wet track or cold road surface, the slow speed handling would deteriorate further.
The Opel Zafira is a compact MPV engineered and produced by the German automaker Opel. The Zafira is branded as Vauxhall, and Chevrolet, depending on the market. In Japan, the Zafira was sold as Subaru Traviq. The car first appeared in 1999, and a second generation model was introduced in 2005. The Opel Zafira is produced in Bochum in Germany. The Opel Zafira has seven seats arranged in three rows, the back row of which can be folded into the floor to create more space, individually or together, rather than requiring that the extra seats be physically removed from the vehicle. The system was named Flex 7.The first generation of Zafira is usually referred to as Zafira A, as is customary for Opel models. The car was based on the same platform as the 1998 Astra G/B and shared much in common with that car. The Zafira A body was used in GM's concept hydrogen-powered fuel cell vehicle the HydroGen3. The Opel Zafira A was replaced by Zafira B in Europe and Japan from 2005, but is still sold in most other markets, except for Australia and New Zealand, where the model was cancelled altogether. The Zafira was sold in the Philippines from 2001 to 2005, being the last European-based Opel car to be sold in the Philippines after they stopped selling the Opel Astra in 2003.The Opel Zafira comes with a variety of engines adopted from the Astra. For Europe, there was a CNG-powered version and a 200 hp turbocharged version by the Opel Performance Center. In Brazil, the Zafira is also available with a flexible fuel engine. European versions of the Zafira had these engines:
