Bonjour, we are looking forward to young people and a change of vehicle. We are currently on the road in a touran and have learned to love the place. We have brought the Touran ( 1.6 TDi / 105 hp / BMT ) since Dec. 2012 and 155Tkm to the clock. Now we are looking for something new and would like to drive a Frenchman. From the design, space, price and engine we like the new C4 Grand Picasso with the 150hp diesel engine very well. After studying the forum, however, always meh r the doubts – a question which moves me as a driver: Is the engine fully gas-proof? Should mean – I drive very often long distances (mostly at night or the early morning hours ) – where is free given I also let the engine run ( as far as one can talk about it with a Touran with 105 hp ) – longer distances with 180km/h – 190km/h ( according to Tacho ) the Touran has so far always survived without complaint. Before that I had a Opel Astra H 1.9 CDTi which my full gas escapades also very much well survived – my question: Can I expect the same from the PSA engines + transmissions? Are the brakes sufficiently dimensioned to brake down a 7 seat safely even from fast driving? I always ride my turbos warm and let it go the last kilometers always calmly so that the turbo can cool down – oil change is also always done regularly (usually 2 times a year). Thank you for your feedback Markus
