Új Ferrari, az F430 utódja....
4500ccm-es 570LE-s V8-as benzinmotor, 13.7-es átlagfogyasztással 1400kg önsúllyal.
Ez nagyon durva.....
1470kg-os 3.0 V6-os 240LE-s alfám eszik ennyit atlagban :)

The new 4499 cc V8 is the first Ferrari direct injection engine to be mid-rear
mounted. It has a very low piston compression height typical of racing engines
which contributed to achieving its compression ratio of 12.5:1. Equipped with
the traditional flat-plane crankshaft, the engine delivers 570 CV at 9000 rpm
and, with an outstanding power output of 127 CV/litre, sets a new benchmark not
only for the whole Ferrari range and the history of company, but also for the
entire market segment. Maximum torque is 540 Nm at 6000 rpm, over 80 per cent of
which is available from 3250 rpm. Specific torque is a record 120 Nm/litre.
However, what is truly extraordinary is the amount of torque available while
still maintaining high levels of power at low revs.
The car’s soundtrack is also typical Ferrari, with an exciting, powerful growl
emerging from the engine before it channels through to the exhaust’s three rear
tailpipes.
The 458 Italia is equipped with the seven-speed dual-clutch transmission which
increases performance whilst providing very smooth shifts even at full throttle.
The engineers have developed specific, sportier gear ratios to match the power
and torque curves of the new V8, guaranteeing high torque even at lower engine
speeds and allowing the car to reach its maximum speed in top gear.
This new Ferrari is also a major leap forward when it comes to cutting
emissions. Despite the fact that the new engine is significantly more powerful
than the V8s that preceded it, the Ferrari 458 Italia produces just 320 g/km of
CO2 and fuel consumption is 13.7 l/100 km (combined cycle), the best in the
entire segment.
The engineers also focused on weight reduction during the design phase for
similar reasons. Consequently, the Ferrari 458 Italia has a dry weight of 1380
kg with a power-to-weight ratio of 2.42 kg/CV. Weight distribution is also
optimal with 58 per cent over the rear axle. The result of the engineers’
endeavours can be summed up in to two simple statistics which together perfectly
encapsulate the Ferrari 458 Italia’s exceptional performance: 0-100 km/h
acceleration in under 3.4 seconds and a maximum speed in excess of 325 km/h.
