Offered are a head protection system, six-point harnesses for the driver and passenger, compatible with a HANS device, and is designed with a central safety cell made of a high-strength steel roll hoop with a fire system. The dashboard is multi-function with race data logging and speed sensors for traction control and launch control. 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 (13.9 in) steel brake discs, with six-piston and four-piston calipers front and rear, respectively. The brake bias pedal box is fully adjustable and brake pads are available in various compounds. The T1 sports a bespoke 3.5-litre, all-aluminum, naturally-aspirated V8 engine, lubricated via a dry sump system. The design of the engine has gone through several changes, previously including a smaller 2.4-litre supercharged unit. It generates a maximum power of 575 brake horsepower (583 PS/429 kW) 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 brake horsepower per tonne. The engine is controlled via a fully tunable Pectel 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 is reported to be capable of exceeding an estimated maximum speed of 322 kilometres per hour (200 mph) on a low downforce setup. From a standing start, it has an estimated 0–96 kilometres per hour (0–60 mph) under 2.5 seconds and onto 160 kilometres per hour (100 mph) under 5 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. On November 11, 2007, the T1 surpassed the Top Gear Power Board leader's time of 1:17.6, held by the Koenigsegg CCX, with a time of 1:10.6. Though immediately having declared the time and placed it on the Power Board, presenter Jeremy Clarkson removed the record because it did not meet the show's rule that the car must be able to go over a sleeping policeman, despite it being street legal.However, Caparo has indicated that the production version has an adjustable ride height and is capable of passing over sleeping policemen.
