Before the Bugatti Veyron
◦Despite it’s similar top speed
◦No Turbocharger
◦No 4WD
◦No traction control
◦No ABS
◦No flappy-pedal electronic controlled gear box

Concepts
◦ Nothing was to get in the way of the driving Experience◦ Driver sits in the middle ◦ Completely in control
◦ Built without compromise
◦ Low weight & High Power◦ Carbon Fiber, Titanium, Gold, Magnesium, Kevlar◦ Engine type: V12

Chassis and Body
◦ First production road car to have a monocoque of carbon fiber reinforced plastic (CFRP)
◦ Attached points of suspension Aluminum and Magnesium directly on the CFRP
◦ ProblemEngine produces ↑Temperature CFRP Mechanically stressed with high heat transference effects Line the engine bay with gold

Engine
◦ BMW V12 6.1L627 hp at 7400 rpm and Torque 651N.m at 5600 rpm
◦ Built especially for this car by BMW
◦ Gordon Murray insisted: Naturally aspired
◦ Turbocharger ↑ power but also ↑Complexity and ↓reliability and drive control

Aerodynamics ◦ Drag Coefficient: 0.32< 0.36 (Bulgatti Veyron)
◦ No wing however overall design and rear diffuser exploits ground effect down force
◦ Rear electric Kevlar fans ↓pressure and cool engine
◦ Top of the vehicle there is an intake pressure air to the engine

Aerodynamics
◦ Ducts assisted by Kevlar electric suction to cool front breaks
◦ Dynamic rear spoiler ◦ 40 mph (64 km/h) brake line pressure 0.32 to 0.39 Cd
◦ Attempt to balance center of gravity
◦ High pressure airflow Cooling rear breaks

Suspension
◦Comfortable yet performance oriented (road car)◦ Not as stiff and low as that of a true track machine would
increase noise and vibration
◦Considered but no used computer controlled suspension◦ ↑ complexity
◦ ↑ weight
◦ Loss of predictability (Driving experience)

Breaks
◦Unassisted, vented and cross-drilled brake discs
◦Servo-assisted ABS Not used◦ ↑ complexity
◦ ↑ weight
◦ Reduce break feel (Driving experience)
◦ Ceramic carbon brakes were used later in F1 GTR
