The 4499 cc V8 engine
powering the Ferrari 458 Italia has won two categories
in the prestigious 2011 International Engine
of the Year Awards, taking the accolade of Best
Performance Engine as well as winning the Above
4-litre category.
The jury for the awards
is made up of 76 motoring journalists drawn from 36
countries who assess engineering excellence in engines
in terms of driveability, performance, economy and
refinement. In assigning the awards the jury also
praised the 458 Italia’s engine for its unmistakable
sound. The awards were received on the occasion of
Engine Expo 2011 in Stuttgart, their thirteenth
consecutive year at the Stuttgart Messe, by Jean Jacques
His, head of Ferrari powertrain department.
Ferrari’s dry-sump, flat-crank, 90-degree V8 sets a
number of firsts for a naturally-aspirated engine of
this displacement. Representing the peak of engine
technology, the V8 reaches a maximum of 9,000 rpm – a
first on a road car – with a high 12.5:1 compression
ratio and maximum power output of 570 CV. This equates
to an outstanding power output of 127 CV/litre, a new
benchmark. The torque available - 540 Nm at 6000 rpm,
with over 80 per cent available from 3250 rpm – ensures
rapid pick-up from all revs. The specific torque output
of 120 Nm/l is another record.
The design of the engine components has been influenced
by the carry-over of racing technology – F1 in
particular – for maximum fluid-dynamic efficiency in
order to achieve both performance and fuel consumption
objectives, and meet the most stringent international
emissions restrictions. With the introduction of the
HELE (High Emotions Low Emissions) system, the 570 CV V8
now produces a best-in-class 275 g/km of C02 with fuel
consumption of just 11.8 l/100 km (ECE + EUDC combined
cycle).
