Citroën has announced the UK launch of a new C2 Stop & Start model, and is offering a cashback incentive of £1,696 (US$2,963) to buyers of all Citroën Stop & Start models (C2 and C3) sufficient to cover one year’s London Congestion Charge.
The Stop & Start technology, first introduced on the C3 in 2004, switches the engine off when the car is at standstill, offering up to a 15% reduction in fuel consumption in heavy traffic, according to Citroën.
The system delivers about 42 mpg US on a combined cycle, and reduces CO2 emissions by about 10% compared to the rest of the C2 gasoline line-up.
The Stop & Start system turns the engine off as the vehicle comes to a halt and then restarts the engine in just 400 milliseconds the moment the driver takes his or her foot from the brake pedal, allowing the car to accelerate away as normal.
The system uses a reversible starter/alternator that acts as a standard alternator one minute—driven by the engine to charge the battery—but, when required, then acts as a starter motor, driven by the battery to re-start the engine. The system can be easily deactivated via a button on the dash.
This C2 is equipped with a new generation SensoDrive automated gearbox, with paddleshift gearchange and automatic function, and a 90hp (67kW) 1.4i 16V gasoline engine.
Citroën unveiled the C2 Stop & Start at the 2005 Frankfurt auto show. Starting price in the UK is £10,690 (US$18,674), not including the cashback incentive.
