The engine has been developed
by Lamborghini to produce 641bhp and 627 lb ft of torque, thanks to
new turbos, cams and
cylinder heads amongst other items, which is enough to blast the 2.2 - ton Urus to 62mph from rest in just 3.6 seconds.

new cylinder -
head design and a
new, sculpted - piston design that is an integral contributor to the high - compression, mixture motion parameters enabled
by direct injection.
This power gain was achieved
by modified inlet ports in the
cylinder head,
new injection nozzles and higher fuel pressure.

by Tenn that Subaru had refined the Legacy's engine with
new cylinder heads and intake manifolds.
The engine, based on the well tried and tested all alloy V8 designed
by Tadek Marek with its racing pedigree, was heavily revised with entirely
new cylinder heads with four valves per
cylinder (last used
by Aston Martin in 1921 - 2) for better breathing and to overcome power losses inevitable with the use of catalytic converters.
