But numbers dont lie and the Sti was 0.2 tenths faster than the Evo x. Remember that the car the stig drove was the 300hp and not the tuned one Jeremy was.

The 5.0 V10?

Wiki says

It is powered a modified V10 petrol engine from the current S6 and S8. The engine is an all-aluminium alloy 4991 cc 90° V10 twin-turbocharged Fuel Stratified Injection (FSI), with a dry-sump lubrication system, and a unique firing order. It has four valves per cylinder, with twin chain-driven double overhead camshafts, and variable valve timing for both inlet and exhaust camshafts. Charged intake air is cooled with two side-mounted intercoolers (SMIC)s. The engine produces 580 PS (427 kW/572 bhp) at 6,250 to 6,700 rpm, and 650 N·m (479 ft·lbf) torque from 1,500 to 6,250 rpm. Engine management is by way of Bosch Motronic ME 9.1.2 engine control unit, incorporating two integrated control units which act as "master" and "slave" concepts. It also uses mapped direct ignition with ten individual coils, an electronic drive by wire throttle, cylinder-selective knock control, and cylinder bank adaptive lambda control, utilising eight lambda sensors.

The RS6 overtakes the position (in power output) from the BMW M5, making about 70 bhp (52 kW) and 150 Nm more than BMW's naturally-aspirated V10 engine.
