D4FT
In an effort to produce a cost-effective fuel efficient engine Renault introduced a turbocharged version of the D4F, the D4FT, in 2007. Renault named it the 1.2 TCE (Turbo Control Efficiency). This engine features revised 16-valve heads and stronger internals to handle the higher stress caused by turbocharging, resulting in 101 PS (74 kW; 100 hp) at 5500 rpm and 145 N·m (107 lb·ft) at 3000 rpm.
Renault created the break by suggesting downsizing on petrol engines, with the range of TCe engines (Turbo Control efficiency). Tce engine - TCe 100, the best 100 bhp (75 kW; 101 PS) petrol engine due to its driving pleasure and moderate fuel consumption. The TCe petrol engine (Turbo Control efficiency) offers the power output of a 1.4L engine, the torque of a 1.6L engine and the fuel consumption of a 1.2L engine. It is responsive, flexible and has power in reserve while displaying the lowest fuel consumption figures for a 100 bhp (75 kW; 101 PS) petrol engine. It emits only 137 g/Km of CO2 on Clio 3 and 140 g/km of CO2 on Modus and the Twingo GT. These unique qualities are obtained thanks to the combination of a 1.2L capacity engine with a low inertia turbocharger whose response time is reduced to the minimum, through the use of a turbine and a small diameter compressor.It produces 91 to 107 PS (90 to 106 hp) an 78 kW (106 PS; 105 hp).
The turbocharger includes an "overpower" feature which temporarily boosts power output in 2nd, 3rd and 4th gears at engine speeds of more than 4,500rpm (5hp extra power and 6Nm extra torque).
It is fitted to the following vehicles:
- 2007–present Renault Twingo
- 2007–present Renault Clio
- 2007–present Renault Modus
