BMW joins the mirrorless car club at CES

Another item the future promised us is finally arriving: cameras for rearview mirrors. It's coming on the Cadillac CT6, Audi played around with the idea in its Le Mans racers, and Tesla has plans to get in on the action. And now add BMW to that list with the i8 Mirrorless concept revealed at the 2016 Consumer Electronics Show in Las Vegas. In BMW's scheme, three cameras replace the mirrors. One big adjustment from years of automotive convention is the lack of any side glances for the driver. A display in place of the conventional rearview mirror shows a composite wide-angle image. Imminent hazards, such as a vehicle in the blind spot, are shown with yellow warning icons. Previous mirrorless designs have mounted cameras flush with the body, but the i8 Mirrorless uses wing-like side cameras. They also serve as turn signal indicators. We assume that the narrow profile is more aerodynamic than the housing for a large piece of reflective glass. Also in BMW's CES bag of tricks is the BMW i3 Extended Rearview Mirror. This uses a rear-facing, roof-mounted camera that overlays images on the conventional interior mirror. But we do have some questions – what happens when the cameras get dirty? Mirrors still work even when partially obscured by dirt. And when will these ideas see production? Stay tuned as we'll follow up with answers from BMW's booth on the CES show floor soon.

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

2015 BMW 4 Series convertibles recalled to fix airbag programming woes

A problem with the airbags on the 4 Series convertible has promoted BMW and the National Highway Traffic Safety Administration to issue a recall for some 2,000 vehicles across the United States. The issue, according to the notice below, relates to the driver's side front airbag, whose timing for deployment may be off. And if the airbag doesn't deploy at the right time in the event of a crash, that's more likely to result in an injury. As a result, BMW of North America is calling in 2,067 vehicles – specifically the 428i, 428i xDrive, 435i and 435i xDrive convertibles of the 2015 model year and manufactured between October 22, 2014, and February 27, 2015. Those units will simply need to have the software in the airbag control module reset, and will begin undertaking that process in April.Related Video: Report Receipt Date: MAR 13, 2015 NHTSA Campaign Number: 15V148000 Component(s): AIR BAGS Potential Number of Units Affected: 2,067 Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America, LLC (BMW) is recalling certain model year 2015 428i Convertible, 428i xDrive Convertible, 435i Convertible, and 435i xDrive Convertible vehicles manufactured October 22, 2014, to February 27, 2015. Due to a programming error, the driver's front air bag deployment timing may be incorrect. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection." CONSEQUENCE: If the driver's front air bag deployment timing is incorrect, there is an increased risk of personal injury in the event of a vehicle crash. REMEDY: BMW will notify owners, and dealers will reprogram the air bag control module with corrected software version, free of charge. The recall is expected to begin in April 2015. Owners may contact BMW customer service at 1-800-525-7417. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
