MERCEDES-BENZ has unveiled two new third-generation plug-in hybrids - the GLE 350 de 4MATIC and GLC 300 e 4MATIC.

Thanks to a battery with a capacity of 31.2kWh, the GLE 250 is capable of over 62 miles in pure electric mode. It also has a top speed of 100mph under electric power. Its four-cylinder diesel engine emits just 29g/km of CO2.

There is no impact on the luggage compartment, the capacity of which is still generous at up to 1,915 litres.

The proportion of electric driving is not only increased by the long range, but also by rapid recharging en route.

To this end the SUV has a combined charging socket for alternating current (AC) and direct current (DC) charging. At corresponding DC charging stations, the battery can be charged to 80 per cent capacity in around 20 minutes.

With a total system output of 320hp and up to 700Nm of torque, its top speed is 130mph, with a 0-62mph sprint of 6.8 seconds.

The latest GLC has a sportier look and is now fitted with LED high performance headlamps as standard, though they are now smaller and flatter. Redesigned all-LED tail lights are also included as standard.

Mercedes says the the GLC was designed for space-saving integration of a battery. The result is a large, level luggage compartment with a capacity of 395-1,445 litres, which is is only just below that of other GLCs.
