Porsche unveils super-fast plug-in hybrid

Porsche unveils super-fast plug-in hybrid

Meet the planet’s fastest, most desirable plug-in hybrid; The Porsche 918.

With a mind bending 661kW available the 918 gets to 100km/h in 2.8 seconds, all while using 3.0 litres of premium unleaded per 100km.

‘E-Power’ mode is the default operating mode and depending on load, the 918 Spyder can cover between 10 and 20 miles purely on electric power.

Even in pure electric mode, the 918 Spyder accelerates from 0 – 100km/h in under seven seconds.

In ‘Hybrid’ mode, the electric motors and combustion engine work alternately, focusing on achieving maximum efficiency and minimum fuel consumption.

The power output of the individual drive components is modified in line with the current driving situation and the required performance level. Hybrid mode is typically used for fuel-efficient driving.

If more dynamic performance is required, the power units in the 918 Spyder switch over to ‘Sport Hybrid’ mode.

The combustion engine now operates continuously, representing the main propulsive force.

The electric motors are activated to support acceleration through the electric boost function, or at points when the operating point of the combustion engine can be optimised for greater efficiency.

This mode focuses on performance and a sporty driving experience at top speeds.

‘Race Hybrid’ is the mode for maximum performance combined with an especially sporting driving experience.

The combustion engine is chiefly used under high load, and charges the battery whenever the driver does not require maximum power. In this mode, the electric motors also provide additional support in the form of boosting.

The gearshift programme of the Porsche PDK is also designed for even sportier driving.

The electric motors are used up to the maximum power output limit to deliver the best possible performance for the race track.

The battery charging condition is not kept constant and instead fluctuates over the entire charge range. In contrast to ‘Sport Hybrid’ mode, the electric motors run at their maximum power output limit for a short period for enhanced boost performance.

This increased output is balanced out by the fact that the combustion engine charges the battery more intensively. The electric power boost is thus always available to the driver even for several very fast laps.

The ‘Hot Lap’ button in the centre of the map switch releases the final reserves of the 918 Spyder and can only be activated in ‘Race Hybrid’ mode.

Similar to a motor sports qualification mode, ‘Race Hybrid’ pushes the traction battery to its maximum power output limits for a few fast laps. This mode uses all of the available energy in the battery.
