Powertrain
Due to the Exeo being derived from the Audi B7 A4, it shares the same fundamental powertrain layout. It has engines mounted at the front, and they are oriented longitudinally, i.e.: "north-south", rather than the "east-west" transverse engine layout used in the remainder of the SEAT range. The gearboxes are of a transaxle type (containing the gearbox, along with the front final drive and differential), and are also mounted longitudinally at the rear of the engine. For the 1.8 litre 20 valve Turbo petrol engine, one side-mounted intercooler (SMIC) is fitted to the lower front left of the car, below the left headlamp. For the 2.0 TSI petrol, along with the 105 and 125 kilowatts (143 and 170 PS; 141 and 168 bhp) and 2.0 litre Turbocharged Direct Injection diesel engines, these utilise two SMICs, one below the left and right headlamps. All diesel engine variants are common rail (CR) Turbocharged Direct Injection (TDI) engines and includes an exhaust catalytic converter along with a diesel particulate filter (DPF).
Transmission options initially included only a six-speed manual gearbox. Shortly after launch, the LuK-originated multitronic continuously variable transmission (CVT), with selectable six- or seven-speeds, became available on models equipped with the 2.0 TSI petrol and 2.0 TDI diesel engines. Distribution of the engine torque to the driven roadwheels is only via the front wheels, and there is not a four-wheel drive offering - which the Audi A4 utilised as an option in its 'trademark' quattro (four wheel drive system).
