BMW Shanghai: Driving in mega cities, designing the future and more

The BMW enclave is a suitable mix of high-tech and throwback cool.
A few days before the Shanghai Motor Show kicked off, we were part of an international group of media that was invited to have a look at the BMW Designworks Shanghai Studio and ConnectedDrive Lab facility. The building that BMW found to house its Chinese think tank is in a lovely part of Shanghai known as the former French Concession. The late 1890s and early 1900s French architectural style, brick-paved streets and tree-lined spaces feel a world apart from the ultra-modern heart of Shanghai, and the BMW enclave is a suitable mix of high-tech and throwback cool.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

BMW won't build M4 Gran Coupe

Over the last few years, it feels like BMW has looked at its lineup and decided to offer a vehicle in every possible segment that it can find, no matter how small. The company is finally showing some restraint, though, at least when it comes to the high performance M division. For example, don't expect to see an M4 Gran Coupe at your local BMW dealer in the future.
M GmbH sales chief Jörg Bartels told Cars Guide in Australia, "It was definitely considered, but there is no plan to build an M4 Gran Coupe." The sport sedan just wouldn't make financial sense, he said. BMW already builds the M3 and M4 at separate factories, adding a third for such a niche model would be too much. Plus, the M3 already fills out the segment.
If you wanted an M model with a bit more storage space in the back, Bartels dashed those dreams, as well. He said that there isn't an M3 Gran Turismo hatchback in the pipeline, either.
