Hybrid-Style Idle-Stop Technology Added to BMW 1-Series

The environment is definitely a hot button issue… probably the hottest. A steady stream oflip service gets paid to this topic, with headlines ranging from climate change theories and remedies to the latest in green technologies. The automotive industry is no exception. Instead of remaining complacently on the sidelines, this year’s auto show circuit confirmed every major manufacturer’s dedication to environmental responsibility when prominent environmentally focused displays were showcased within their exhibits.

There are different approaches to ecologically sound transportation, running the gamut from small and efficient compacts to advanced alternative fuel concept cars powered by hydrogen. By now we’re all familiar with hybrid vehicles; their popularity has ensured instant recognition by most of the motoring public. As common as they are, hybrids are often had for a premium over the price of a given car’s gasoline powered counterpart. Still, many believe that we shouldn’t have to spend more just because we want to “go green”.

BMW is receptive to your concerns, and has responded with its newly introduced 1-Series compact coupled to popular hybrid technology, in this instance called Stop-Start. The aptly named system from Bosch will do just that to the Bimmer’s engine when making frequent stops during city driving, shutting down at idle. By doing so, BMW projects an 8 percent improvement in fuel economy, and a significant drop in tailpipe emissions. Simplicity of the components was specified by engineers; fancy batteries or sophisticated drivetrain components were not considered. The engine cycling on and off had to be seamless, with durability to match. According to BMW’s press release, the only mechanical change needed to implement Stop-Start is a slightly different starter motor: “The starter’s improved-performance electric motor, low noise and stronger pinion-engaging mechanism ensure that the engine starts reliably, quickly and quietly.”

Those intrigued by the German automaker’s new approach to environmental kindness may be disappointed to learn that plans of selling the 1-Series in the U.S. have not been confirmed. Not only that, but if it does get sold here there’s also no word on whether or not they would offer the Stop-Start option to American buyers. Despite this, environmentally conscious consumers should take heart in seeing that manufacturers are looking at this problem from many different angles. While the consumer benefits by having more choices when searching out greener vehicles, an 8 percent fuel savings is only step-one towards BMW’s upcoming dual-mode hybrid system being co-developed with DaimlerChrysler and General Motors, which, while adding cost and complexity, will significantly reduce any given vehicle’s environmental footprint. If BMW chooses to couple this technology to other existing fuel saving tricks, such as cylinder deactivation, the possibility of serious fuel savings becomes strong. Stay tuned for updates on BMW’s diminutive five-door and whether or not the car, let alone the Stop-Start technology makes it to our market. With close to every last one of its German competitors selling entry-level luxury models in the 1’s segment within the U.S. (except for M-B that only sells its B-Class in Canada), however, it only makes sense that the brand will finally bite the bullet and offer the car to what seems like a very willing American public.
