Thomas Weber, a Daimler board member in charge of research and development told Automotive News, "All our vehicles will have turbocharged engines in series production by the end of 2010 at the latest."
Glad I got mine when I did! My other Daimler product has a turbo and they can be a bit finicky when you hit the higher km.....and need special treatment when stopping the engine.
The only special treatment is a short idle after a long high speed run, but I always allowed all my cars to have the temperature equalize. Years ago it was recommended that the engine was run for at least 5 minutes to prevent the oil from breaking down around the bearings. With modern oil even non synthetic the oil does not harden and turn to coke.
It's surprising how many people will punt up the Hope Slide on Highway 3 in a turbo and stop at the top and turn off their engine immediately when the turbo is practically red hot.....not to mention the all Audi 5000 Turbos that burnt up on the Coquihalla in the late 1980s A little care is still needed, even with water-cooled bearings.
Sadly I owned an Audi 5000 (cost $5000 a year in repairs) and the fire potential was eliminated by moving a wiring harness that was within inches of the exhaust. Because of reports of sudden acceleration a safety interlock was placed in the transmission, this is now used in virtually all cars so the old Audi did have its use. The gas pedal and the brake pedal where located at the same height and very close to each other, thus it was very easy to apply both at the same time.
Modern oils and water cooled turbos (convection cooling) dont have the problems of old school turbo coking. I'm sure the owners manuals would have mention something if it was an issue. I wouldnt worry too much about idling before shutdown.
It's not like the MB engineers forgot about it when designing the drivetrain.
