“With an aggressive and addictive character,
this engine will always make you smile”
Giannis Charpidis, 4Wheels

The overall winner of the International Engine
of the Year title for the past two years, the 5-litre V10 from
BMW that
powers the M5 and M6, returns in 2007 to secure the Above 4-litre
category title for the third consecutive year. The victory means
that in all, the unit has now won eight ‘Engine Oscars’.
The 507bhp, 520Nm powerhouse
continues to be showered with praise
by Awards judges. “Still lust-worthy, and
a technological triumph for naturally
aspirated engines,” said Chris Walton from Edmunds.com.
“A great engine and an even greater sound,” added
Auto News Agency’s Mohamed Sheta.
The object of their affection is a V10 with a 90° vee angle,
which allows it to be optimally placed lower under the bonnet
of the M5 or M6 that it powers. It boasts one-piece, four-valve,
aluminium cylinder heads, while the valvetrain components, such
as the 5mm valve shafts, have been engineered for low mass.
Production techniques have also played their part
in keeping the weight low – the cylinder crankcases are
cast using the low-
pressure gravity die method and
made from a lightweight hypereutectic
aluminium silicon alloy.
The V10’s enduring popularity is
particularly impressive given that the engine had two strong
new challengers
in 2007 in the form of Ferrari’s 6-litre V12 from the
599 GTB and the hybrid 5-litre V8 in the Lexus LS600h. Nevertheless,
in the opinion of the jury the victory
was still a clear one. As Jake Venter from South Africa’s
CAR put it, “Nothing has appeared in the last 12 months
to rival the large doses of Formula 1 technology that are displayed
in the mighty V10.” |
