STUTTGART: The Mercedes-Benz compact-car family gets three new plug-in hybrids, namely the CLA 250 e Coupé, CLA 250 e Shooting Brake and GLA 250 e.
The new compact cars with a third-generation hybrid drive system highlights:
> Electric operating ranges of 71-79 km (NEDC)
> Electric output 75 kW
> System output 160 kW
> System torque 450 Nm
> Alternating-current (AC) charging system up to 7.4 kW
>Direct-current (DC) charging system at max. 24 kW
> Hardly any restrictions on the load compartment
They feature transversely mounted engines, and a compact hybrid traction head was developed for the 8G-DCT dual clutch transmission.
For the first time on a Mercedes-Benz vehicle, the combustion engine is started by the electric motor - the compact hybrids do not have a separate 12-volt starter.
The electric tech achieves 75 kW, and together with the 1.33-litre four-cylinder engine, this produces a system output of 160 kW (218 hp) and a system torque of 450 Nm.
The new compact cars can be charged with alternating current or direct current.
This means that the compact plug-in hybrids can be charged at a 7.4 kW wallbox with alternating current (AC) within 1 h 45 min from 10-100 percent SoC (State of Charge).
For direct-current (DC) charging at 24 kW, the battery can be charged from 10-80 percent SoC in around 25 minutes.
The batteries are supplied by the wholly owned Daimler subsidiary Deutsche ACCUMOTIVE.
The high-voltage battery is water-cooled and weighs 150 kg.
