Meet the inventor of the BMW 3 Series wagon

It's hard to imagine, but once upon a time, there were only two BMW 3 Series variants: the coupe and sedan. Back before gran coupes, convertibles and yes, even touring models were available, buyers could only get their 3 Series fix if it came with two or four doors and a fixed roof. Back in the mid '80s, BMW engineer Max Reisbock was having some trouble fitting his whole family into his four door. Rather than suck it up and buy a van, he picked up a wrecked 3 Series and got to cutting in a buddy's garage. Months later, he had the very first 3 Series Touring ever built.
At first, he kept the the car to himself, using it to haul friends and family around, but he eventually showed it off to his friends at work. When the BMW executives found out about his project, they called him up to take a closer look. After putting an eyeball on the car, they took it, copied his design, made a few tweaks and quickly rolled out the first production 3 Series Touring. How's that for validation? Check out the video below for Reisbock's story.

2011 BMW 1 Series M Coupe now more expensive than when new

At the end of the day, your friendly Autoblog editors are car guys, just like you. So, while we might have more of an opportunity to test some of the most interesting vehicles on the new car scene than does your average gear head, we can still be found whiling away those long afternoon hours looking at used cars and thinking about what could be.
Just the other day, we had a vivid reminder about one of our dream cars from the very recent past, the 2011 BMW 1 Series M Coupe. If you didn't catch it, Michael Harley had a great time testing and reviewing the new Dinan S3-R version of the car, which throws an impressively engineered turbo and suspension tune on a BMW that was damn near perfect out of the box.
In the Comments section of that review, a few savvy Autoblog readers pointed out that our estimated price for a used donor car, set at $50,000, was low. Odd, we thought, as the car retailed for less than $50k ($46,135) when it was new in 2011. So we started checking around.

BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.
