The heart of the SQ5’s monster pace is its 3.0-litre bi-turbo TDI engine, which delivers 313PS (309bhp) at 3900-4500rpm and 650Nm (497lb ft) at 1450-2800rpm. Performance figures are interesting – 0-62mph in 5.1 seconds and a governed 155mph maximum speed. Timing and lift of the intake camshafts, the pistons, their oil-jet cooling and the piston pins have also been specially designed to cope with the additional power.
