|The 1.6 litre THP 150 bhp (Turbo High Pressure) 16v engine (launched on 207) launched a new family of petrol engines, the result of the co-operation between the PSA Peugeot CitroŽn and BMW Group.
The aim of this partnership is to develop petrol engines which are equipped with innovative technologies that offer high levels of performance - with low fuel consumption - at the same time as meeting the cost constraints imposed in the lower and lower-medium vehicle market segments.
Each partner has contributed the best of their skill and expertise, whether it be in engine design or in manufacturing processes.
The engine is produced at the PSA Peugeot CitroŽn factory in Douvrin, France.
The 1.6 litre THP engine has a sixteen valve cylinder head with two overhead camshafts and 4 cylinders displacing 1598 cc. It produces a maximum power output of 110 kW (150 bhp) at 5800 rpm.
The choice of a 4-cylinder 1.6 litre engine was made because small turbocharged engines with a high specific power output, offer a significant advantage in terms of fuel consumption over normally aspirated engines with a larger displacement. This downsizing strategy is also in line with Peugeot's HDi diesel engine strategy.
This new petrol engine uses very innovative technology and is capable of making the 207, for instance, as dynamic and enjoyable to drive as a car with a larger engine.
Its performance is evidence of this as with just the driver on board, it only takes 29.4s to cover the standing start 1,000 m and accelerates from 80 to 120 km/h in 5th gear takes only 8.2 s (in comparison, the 206 S16, despite a weight advantage, took 10.1 s). The maximum speed of 210 km/h is reached in 5th gear. The innovative technology used in this engine and the high torque output available at low engine speeds, helps reduce the fuel consumption to (7.0 l /100 km in the combined cycle compared with 7.7 l /100 km for the 206 S16) and makes it possible to reduce the CO2 emissions (166 g/km compared with 185 g/km for the 206 S16).
