Mercedes-Benz India has now added a new diesel variant of its most selling C-class, the C250d. While the car doesn't have much exterior changes, the big difference lies under the hood. It’s the new 2.2 Litre engine which boasts a power of 204 Bhp and delivers 500 Nm of torque with an all new 9G – Tronic Gearbox which is quick and very responsive.
