Systematically electrified for an outstanding driving experience – the integrated starter-alternator boosts and recovers energy, while the 48-volt on-board electrical system supplies the power consumers and the additional compressor provides torque from just above idle speed. More than a bonus: the smooth running of the six in-line cylinders.

Key features:

• Crankcase and cylinder head made of aluminium, incorporating zirconium alloys to dissipate the heat more efficiently for maximum engine output and stability even at the limits
• Highly efficient direct injection system with demand-controlled multiple injection and multi-spark ignition for optimal mixture formation
• Cylinder barrels lined in NANOSLIDE® technology (iron/carbon) – ideal piston lubrication with reduced friction and wear thanks to extremely hard surfaces with minute pores for oil retention
• Twin-scroll turbocharger with air/water charge-air cooling and two-flow exhaust routing - the ducts, each from two cylinders, are separate and come together only just before the turbine.
• This dethrottles the exhaust system and the engine responds more directly to accelerator pedal commands
• Sophisticated acoustic cladding for quieter operation
• An electric additional compressor supplies even more charge pressure and therefore additional torque from just above idle speed
• This bridges the time delay before the large turbocharger goes into powerful action, three times for two seconds or once for 15 seconds per minute
• Impressive start-off with absolutely no turbo lag
• CAMTRONIC with two-stage valve lift switchover – to save fuel, the valve clearance at the intake camshaft is always optimally adapted to the driving mode
• Plastic engine mounts reduce vibration
• Exhaust gas aftertreatment arranged directly on the engine for a more powerful and faster response and less dependence on ambient temperatures or driving style
• Petrol particulate filter reduces minute soot particles and significantly undercuts even the most stringent limits (the only part of the exhaust gas aftertreatment in the underfloor area)
