The chassis was a high-rigidity monocoque design of high-strength alloy and steel, utilising the latest techniques in assembly, with emphasis placed on ease of maintenance and repair. This supported a body which was a full aerodynamic wedge, incorporating side radiators. The interior of the cockpit was covered in fully moulded seat and trim sections, making it exceptionally comfortable and roomy.

The rear suspension incorporated twin radius arms, parallel links, Armstrong adjustable dampers, and fully adjustable spherical bearings throughout. The front suspension was a double-wide-based wishbone design with Armstrong adjustable dampers and fully adjustable spherical bearings throughout. The coil spring units for both front and rear were mounted inboard with "Bowin variable rate spring control".

The P8 was steered by a cam-adjustable magnesium rack and pinion designed by Bowin, with an energy absorbing steering column surmounted by a leather-covered steering wheel. The brakes were Girling 9.75 in (24.8 cm) disc brakes with alloy caliper assemblies. The twin braking system was adjustable for length and had an adjustable-ratio balance control. The rear brakes were mounted inboard on the gearbox to reduce unsprung weight. The wheels were magnesium, with 10 in × 13 in (25 cm × 33 cm) in the front and 12 in × 13 in (30 cm × 33 cm) or 14 in × 13 in (36 cm × 33 cm) in the rear.

It had a wheelbase of 93 in (240 cm), a track of 61 (front) and 63 (rear), and a weight of 800 lb (360 kg) (including the twin cam engine).

The transmission was a Hewland FT2000, providing five speeds and reverse, and it had an alloy adaptor plate. The hydraulic clutch system was complete, up to and including the release mechanism on the gearbox.

The engine was water-cooled by twin, cross-flow, lightweight, side-mounted radiators, with a deaireator control tank and pressure cap. The alloy oil tank was incorporated in the monocoque body and was fitted with antisurge baffles, a deaireator system, alloy pipes, hoses and fittings, and an alloy oil cooler. Fuel was contained in cells in the side panels. Each side had a capacity of 14 US gal (53 L) with a dedicated filter and breather. The P8 was supplied with engine mountings.

The electrical system was powered by a 12 volt, lightweight, aircraft battery, which had a master battery control. It powered a starter solenoid via starter button and switches, as well as an array of instruments, including tachometer (0–10,000 rpm), oil pressure, water temperature, and oil temperature.

All suspension parts were in new Bowin Satin finish, and the other parts were cadmium-plated and stove-enamelled. The body was painted in a colour of the customer's choice.

The Ducati 749 is a 90° V-twin Desmodromic valve actuated engine sport bike built by Ducati Motor Holding between 2003 and 2006. Designed by Pierre Terblanche, the 749 was available as the 749, 749 Dark, 749S, and 749R. It shared many of its parts with the 999, with the exception of a slightly smaller 180/55 profile rear tire, smaller cylinders, and different cylinder heads, giving it a smaller displacement of 748 cc. This smaller engine is higher revving and produces a lower peak horsepower than the larger engine used in the 999. The 749S model, like the 999, incorporates features rarely found on production motorcycles, including adjustable rake and five-position adjustable rearset mounts.

A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations.

The 701 was March's first Formula One design – following their one-off March 693P Formula Three prototype of 1969 – and was designed and built in only three months. The March 701 made its race debut a month after its public unveiling, at the 1970 South African Grand Prix. In total, eleven 701s were constructed, with March supplying many privateer entrants as well as their own works team. The 701's career started well, March drivers taking three wins and three pole positions from the car's first four race entries, but lack of development through the 1970 Formula One season resulted in increasingly poor results as the year wore on. The 701 was superseded by the March 711 in 1971, and made its last World Championship race appearance at the 1971 Italian Grand Prix.
