Citroen has taken to downsizing its supermini engines again, and has announced the introduction of a three-cylinder engines under the PureTech name. These will be available in the C3, DS3 and C-Elysee and will displace either 1-liter or 1.2-liter capacities, producing either 68 or 82 PS.
The engines promise to deliver fuel economy figures of between between 65.7mpg and 61.4mpg (4.3 and 4.6 l/100 km) in the UK combined cycle, putting out somewhere in the range of 99 to 107 grams of CO2 per kilometer. If that all sound familiar, it’s because they’re likely the same units found in the new Peugeot supermini, the 208.
Here are some of the key features of the PureTech engine family:
Here are some of the key features of the PureTech engine family:
- A timing system with two overhead camshafts and four valves per cylinder, controlled directly by two mechanical push rods for enhanced fill-up and efficiency
- Continuous variable hydraulic timing for the intake and exhaust camshafts, for better performance at low and medium engine speeds and optimised fuel consumption
- On the VTi 82 version, a counter-rotating balancer shaft, for reduced vibration and quieter operation
- Electronic management to optimise battery charge, with freewheel alternator operation used to a maximum when it requires no energy expenditure
