Car companies may need to start curbing model proliferation

Looking at the current automotive landscape, especially from German makers, you quickly get the impression that less definitely isn't more. BMW alone offers its 3 Series platform in practically every segment possible, including the regular sedan and 4 Series Gran Coupe, which would seem to be direct competitors. Porsche might be the winner, though, with 20 different variants of the 911 listed for sale on its US website. However, some of this model madness might be reaching an end as companies begin cutting back spending or shifting money to other priorities.
According to Yahoo Finance, the offerings from the German automakers are up 25 percent over the past three years to over 200 models in Europe. The peak is expected to come around 2018 at 230 separate vehicles, according to consulting company PwC.
Amazingly, BMW, which is among the poster children for this model explosion, might be changing its tune. "I'm sure there will be points in the future where we look at certain cars and say, 'Maybe we need to think differently now,'" said head of sales Ian Robertson in an interview, according to Yahoo Finance. The statement certainly sounds shocking coming from a company rumored to have 23 front-wheel-drive vehicles all using a single platform on the way.

Rinspeed previews Budii concept ahead of Geneva show

Every year Frank Rinderknecht and his team at Rinspeed come to the Geneva Motor Show with another fantastical concept car, and next year's will be no exception. Though the show may still be several months away, the Swiss outfit is already giving us a glimpse of what to expect. Rinspeed's latest project is called the Budii, and it aims to "redefine the relationship between man and machine." As you might have guessed, that means driverless technology. Specific details at this point are limited, but the design calls for an electric vehicle with an adaptable cabin featuring drive-by-wire steering wheel. That wheel can swing out of the way to the center of the dashboard or to either side, should driver or passenger (as blurred as those rigid concepts become in this case) wish to take control. Beyond that we don't know much at this point, but the image above seems to indicate it'll be based on the BMW i3. Meanwhile the long list of partners and suppliers suggest it'll feature a design by Mansory, a Harman infotainment system and a Carl F. Bucherer analog clock embedded in the dynamic dashboard. 2015 Geneva Motor Show Rinspeed exhibits "Budii" at the 2015 Geneva Motor Show: "We need to redefine the relationship between man and machine" As far as Swiss automotive visionary Frank M. Rinderknecht is concerned, the breakneck speed of technical developments forces us to redefine our relationship with the automobile. The farsighted Swiss says: "Until now, what we have primarily associated with auto mobility was freedom and individuality. And - consciously or unconsciously - we are prepared to pay a high price in many regards for these privileges. We need only look at the accident statistics." Autonomous driving undoubtedly offers the opportunity to drastically diminish some of the drawbacks of private transport. For example, the number of traffic accidents could drop worldwide. But although it will be less prone to err than humans, even the best technology will not be perfect. "That is something we will have to accept," believes the boss of Rinspeed, the Swiss automotive powerhouse of ideas.

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.
