Lamborghini has unveiled the Asterion LPI 910-4 at the Paris Motor Show today, billed as a ‘technology demonstrator’ and the company’s first plug-in hybrid (PHEV).

In typical Lamborghini style, the Asterion LPI 910-4 name requires a little explanation – LP stands for ‘longitudinale posteriore’, the position of the petrol engine, I stands for ‘ibrido’, the Italian for ‘hybrid’, 910 for the overall power and 4 to denote the 4WD system.

The Asterion is powered firstly by a 5.2-litre V10 FSI petrol engine mounted in the conventional mid position, which by itself produces 610hp and 560Nm of torque.

It’s joined by three electric motors – one as an integrated starter motor and generator (ISG) placed between the V10 engine and its seven-speed dual-clutch transmission, and two further motors mounted on the front axle, drawing their power from the ISG.

The three electric motors combine to provide an additional 300hp, giving a total system power output of an incredible 910hp.  That’s enough to accelerate from 0-62mph in just 3.0 seconds dead, with a top speed of 320 kmh (199 mph).

The system can also provide an all-electric mode with a 50 km (31 mile) driving range and a top speed of 125 kmh (78 mph), and in this mode it draws its power from a lithium battery mounted in the central tunnel.

Remarkably, the result of this electrickery is a fuel consumption figure of 4.12 l/100km (about 68 mpg) and CO2 emissions of just 98 g/km.
