    An all-new engine designed by AUDI AGs high performance subsidiary quattro GmbH, harking back to the original turbocharged five cylinder Audi engines in the "Ur-" Audi Quattro of the 1980s. A world first for a petrol engine, its cylinder block is constructed from compacted vermicular graphite cast iron (GJV/CGI) - first used in Audis large displacement, high performance Turbocharged Direct Injection (TDI) diesel engines.
    parts code prefix/variant: 07K.3; ID code: CEPA
    engine displacement & engine configuration
    2,480 cubic centimetres (151.3 cu in) inline five engine (R5/I5); bore x stroke: 82.5 by 92.8 millimetres (3.25 in Ч 3.65 in), stroke ratio: 0.89:1 - undersquare/long-stroke, 496.1 cc per cylinder; 88 mm (3.46 in) cylinder spacing, 144 degree firing interval, firing order: 1-2-4-5-3, compression ratio: 10.0:1
    cylinder block & crankcase
    GJV-450 compacted vermicular graphite cast iron (GJV/CGI); six main bearings, two-part cast aluminium alloy horizontal-baffled oil sump, simplex roller chain-driven oil pump, die-forged steel crankshaft, forged steel connecting rods, cast aluminium alloy pistons (weight, each, including rings and gudgeon pin: 492 grams (17.4 oz))
    cylinder head & valvetrain
    cast high hot-strength aluminium alloy, modified inlet duct geometry for high tumble values providing superior knock resistance, four valves per cylinder (exhaust valves sodium filled for increased cooling), 20 valves total, low-friction roller finger cam followers with automatic hydraulic valve clearance compensation, simplex roller chain-driven (relay method) light-weight double overhead camshafts (DOHC), variable valve timing with continuous adjusting intake and exhaust camshaft timing of up to 42 degrees from the crankshaft, two-stage 'valvelift' variable lift control for inlet valves, siamesed inlet ports, Audi "RS" 'red' plastic cam cover
    hot-film air mass meter incorporated into air filter housing, cast alloy throttle body with electronically controlled 'drive by wire' throttle butterfly valve, two piece intake manifold with charge movement flaps adjusted by a continuous-action pilot motor, water cooled turbocharger incorporated in exhaust manifold with 64 mm (2.5 in) diameter outlet, generating up to 1.2 bars (17.4 psi) boost, separated central lower front-mounted intercooler (FMIC)
    fuel system
    fully demand-controlled and returnless: fuel tank-mounted low pressure fuel lift pump; Fuel Stratified Injection (FSI): single-piston high-pressure injection pump supplying up to 120 bars (1,740 psi) fuel pressure in the stainless steel common rail fuel rail, five combustion chamber sited direct injection sequential solenoid-controlled fuel injectors, air-guided combustion process, multi-pulse injection with homogeneous mixing, stratified lean-burn operation with excess air at part load, ultra-low sulfur unleaded petrol (ULSP)
    ignition system & engine management
    Beru longlife spark plugs centrally positioned in combustion chamber, mapped direct ignition with five individual direct-acting single spark coils; Bosch Motronic MED electronic engine control unit (ECU), cylinder-selective knock control via two knock sensors, permanent lambda control
    exhaust system
    secondary air injection pump for direct injection into exhaust ports to assist cold start operation, cast iron exhaust manifold (with integrated turbocharger), two primary and two main high-flow sports catalytic converters, two heated oxygen sensors monitoring pre- and post-catalyst exhaust gasses, vacuum-operated map-controlled flap-valves mounted in rear exhaust silencer tail pipes
    length: 494 millimetres (19.4 in), mass: 183 kilograms (403 lb)
    DIN-rated motive power & torque output
    250 kilowatts (340 PS; 335 bhp) @ 5,400-6,500 rpm (specific power of 100.8 kW (137.0 PS; 135.2 bhp) per litre); 450 newton metres (332 ft·lbf) @ 1,600-5,300 rpm; redline: 6,800 rpm
    300 kilowatts (408 PS; 402 bhp) @ 5,400-6,500 rpm; 480 newton metres (354 ft·lbf) @ 1,600-5,300 rpm; redline: 8,000 rpm
