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 M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

BMW crushing ActiveE EVs, saving all batteries

It's unlikely to spark a movement and a movie, the way a certain EV1 did a decade ago, but anyone who's seen Who Killed The Electric Car? will likely cringe at this bit of news. Despite the fact that crushing and recycling old vehicles is standard operating procedure in the auto industry, when EVs are involved, it's always a touchy subject. The next phase will see "all of the lithium-ion batteries being repurposed for Battery Second Life research projects." So, what's the news? Well, the image you see above, which comes from the spotting of 16 smashed BMW ActiveE EVs on flatbed trailers on California Route 91 near Los Angeles, CA. EV advocate Chelsea Sexton told Green Car Reports, "It's all very deja vu, right down to [BMW's] DriveNow promotion as a don't-look-behind-the-curtain distraction – recall GM touting EV1s being donated to museums and universities? – and VINs spray painted on the sides, allowing former drivers to identify their own cars." BMW's take on this is that the ActiveEs were always meant to have a limited lifespan, and their time has come. As spokesman Dave Buchko tells AutoblogGreen, "The learning begun with the ActiveE will transition to the next phase with all of the lithium-ion batteries being repurposed for Battery Second Life research projects." (You can read his full statement below.) Originally, there were 700 ActiveEs leased to Electronauts (give or take). Yahoo! Autos points out that the ActiveEs were originally imported into the US as "pre-production" cars, which means they can't be sold, they can only be used for carsharing projects or re-leased. Eighty of those ActiveEs recently found a second life as vehicles in BMW's DriveNow carsharing fleet in San Francisco (bringing the total of ActiveEs in the program to 150) and "some have also been returned to Munich for additional research markets," Buchko said. The big picture here is that no one should be sad to see these cars go. Yes, they may have had some life left in them, but the rules say their time is done and everything is being done to crush responsibly in accordance with the law. Like Plug In Cars says, we're in a completely different era now than we were when GM crushed all those EV1s a decade ago. Instead of marking the end of a plug-in vehicle program, sending the ActiveEs away to be recycled is a symbol of the evolution and growth of BMW's i Project.
