One of my all-time favorite cars that I reviewed was the BMW 535d that Bosch loaned me a few years ago. http://green.autoblog.com/2007/12/17/in-the-autobloggreen-garage-2007-bmw-535d-yes-its-a-diesel/
That car was powered by a twin-turbocharged version of BMW's marvelous 3.0-liter inline-six diesel that cranked out 286hp and a massive 428 lb-ft of torque. It was both quick and fuel efficient achieving 27 mpg during a week of hard driving.
Yesterday BMW officially launched the first of its long-rumored diesel M models with an even more powerful variant of the 3.0L diesel. The addition of a third turbocharger has bumped up the bottom line to 381 hp and 546 lb-ft which is sufficient to drop the 0-60 time from the 6.4 seconds I recorded in the 535d to just 4.7 seconds in the M550d. The new tri-turbo engine is available in the 5-series sedan and wagon as well as the X5 and X6. I'll take a M550d Touring wagon in Dark Graphite please!
