“With its two variable turbos, this turbo engine generates
incredible performance”

It takes something really quite special
to de-throne BMW’s 3.2-litre, the most successful unit
in International Engine of the Year Awards history, behold the
3.6-litre turbo from Porsche. When all the points were counted,
this engine finished just four points ahead of the BMW M powerplant,
winner of this category for the past six years.
Porsche’s new flat six is a sublime feat of engineering,
combining state-of-the- art technology with epic performance.
Such details as 420bhp on tap prompted Tomaz Porekar of Slovenia’s
Avto Foto Market to say, “One of the greatest flat-six
engines ever produced. Excellent power and perfect for everyday
driving.”
But the Porsche engine is about more than just high power. The
turbo motor
is the first from Porsche to feature exhaust gas turbochargers
with variable turbine geometry, with one turbocharger within
each row of cylinders. Thanks to this technology, the full flow
of exhaust gases can be used to provide optimum charge effect.
The engine’s variable
turbine geometry combines the benefits of small and large turbos,
and offers optimal performance throughout the rev range.
Compressed air produced flows through two intercoolers that
have a 10% larger diameter to accommodate more air. The engine
also features an automatic waste valve that fits in the compressor
housing of the exhaust gas turbocharger to save space. In addition
to the
performance being offered, the turbo can record 12.8L/100km
(22mpg) on the EU combined cycle too.
The last words on the subject go to American Ken Gross, who
comments
simply: “The best 911 engine Turbo ever.” |
