The dynamic 620 cv powerhouse from the family of V8 turbo engines that drives the Ferrari Roma was voted International Engine of theYear for the fourth year running.This was made possible through innovations in new cam profiles, a speed sensor which measures the turbine revolutions and allows the maximum revs per minute to be increased by 5,000 rpm, and the introduction of the Gasoline Particu- late Filter to comply with the strictest Euro 6D anti-pollution standards. The Ferrari Roma accelerates from 0-60 mph in a striking 3.4 seconds with a top speed of 200 mph. It boasts Variable Boost Management, a control software developed by Ferrari that adjusts torque delivery to suit the gear selected, thus delivering increasingly powerful pick-up as the revs rise, whilst optimising fuel con- sumption.As the car goes up through the gears the amount of torque delivered by the engine increases up to 760 Nm in 7th and 8th gear, keeping fuel consumption and emissions down. It is equipped with a new compact 8-speed DCT gearbox which is 6 kg lighter and 20% smaller, delivering 35% more torque than its 7-speed predecessor.As well as reducing fuel consumption and emissions, the shifts are faster and smoother thanks to the use of low-viscosity oil and a dry-sump configuration to minimise fluid-dy- namic efficiency losses.This makes the car more responsive on the open road, but also especially comfortable in town and during stop and start driving situations. In line with Ferrari’s zero turbo lag concept, the Ferrari Roma delivers almost instantaneous throttle response.This to thanks to the compact flat-plate crankshaft which has lower rotating masses to improve fluid-dynamics; compact turbines which have a lower moment of inertia; twin-scroll technology that increases the pressure of the exhaust pulse for maximum power; and the single-piece cast exhaust manifold with equal-length pipes to optimise pressure waves in the turbine and reduce losses.
