2015 BMW M4 Convertible Quick Spin [w/video]

Quite a while ago, we ran a story where our editors disclosed their guilty pleasure cars. There, I admitted my love for the ultra-comfortable Acura RLX. But I have another automotive guilty pleasure, and it's the BMW M4 Convertible, and the droptop M3 that came before it, as well. Whether it's an E46, E93, or the new F83 M4 model, I just love the idea of a droptop M car. It kind of goes back to my Lexus RC F review, where I posit that most consumers buy a car like this solely for the image. To the point of this car, if you're opting for a convertible, you're boldly throwing out any pretense that you bought this car for its performance. It's a different and far grander indulgence than something like a droptop Ford Mustang, Chevrolet Camaro, or even a Corvette, and that's especially the case with the new M4, as I found out after a week at the wheel. Driving Notes Anyone that's listened to me on the Autoblog Podcast knows I've been none too kind about the state of BMW's turbocharged M cars. In effect, they're too easy to drive. In older models, the narrow power band meant you needed to always keep an eye on the tach, lest you fall into a weak zone. But because today's turbocharged M engines are so damn torquey, you can simply mash the throttle, regardless of engine speed or gear, and zoom forward. That's mostly the case here, although with a 7,500-rpm redline, the M4 at least maintains the illusion that you have to keep the revs up. Power delivery is fast and immediate, capable of catapulting the M4 towards the horizon at even half throttle. But more than the brutal power delivery, this latest M entertains with a strange but familiar singing voice. It's an almost feral, straight-six howl, particularly high in the rev range. But because of the single-scroll turbochargers and today's sound-tuning sorcery, the noise here is far richer and complex than what you'd get in a naturally aspirated M car, like the old E46. The turbos hiss and spit, and wide-open-throttle upshifts come with a cackling snap from the quad-tipped exhaust. Despite my belief that M cars' manual transmissions are generally pretty lousy these days, the M4's gearbox is far better than what you'll find in an M5. The clutch is more forgiving than in the larger sedan, too. With a broad catchpoint and a linear action, it feels natural and intuitive to work.

Recharge Wrap-up: Tesla Gigafactory gets high-tech neighbors, BMW i8 still comes with a long wait

Switch plans to build a large data center near the site of Tesla's Gigafactory battery production facility in Reno, Nevada. The 3 million square-foot facility in the Tahoe-Reno Industrial Center will cost $1 billion to build, and eBay is expected to be the main tenant when the first portion is finished in 2016. Apple is also building a data center nearby. One draw for companies like Switch, Apple and Tesla is access to the region's clean power, and the Reno area could become the next big center for high-tech manufacturing. Read more at GigaOm. Daniel Sparks of investing website The Motley Fool has shared his insights after living with the Tesla Model S for four months and 10,000 miles. After driving his 85-kW version through various conditions, including a 2,200-mile road trip, Sparks is optimistic about the car and the company behind it. From his experience, he says that charging is easier than most people believe, and that range anxiety isn't a problem. He calls Tesla's growing Supercharger network a "game changer," citing their quickness, availability and the fact that charging is free for life. He also says that most people seem to know very little about the car. Still, he calls Tesla stock "pricey" with the growth already priced into the shares. Read more at USA Today. The wait for a BMW i8 is about a year, despite efforts to ramp up production. BMW is reducing production of the i3 in order to increase the number of i8s by more than 50 percent for 2015, but the bigger batch won't become available in the US until October. Ludwig Willisch, CEO of BMW North America, says that he doesn't expect cheap gas to slow sales of the i3. He also denies rumors of an i9 positioned above the i8. The new 7 Series appears to be taking some cues from the i8, though, with carbon fiber, magnesium and aluminum construction, as well as improved connectivity. Read more at Automotive News.

What's up with this thought-controlled BMW i3?

Autonomous driving? A car being controlled by just verbal commands? One pilot program is going way beyond that this year with a car that can theoretically be mind-controlled. UK-based insurance-services company MoneySuperMarket is promoting something called "Epic Mind Drive." The project involves a BMW i3 electric vehicle (nice and futuristic) being rigged up with an autonomous driving system. Only instead of the system watching the road, it involves a person sitting in a seat outside of the car with an electroencephalography (EEG) neuro headset connected to the vehicle. In fact, that headset records brain activity and translates it into instructions. Those instructions are converted to radio frequency that's sent to the car to instruct it to perform various speed and turning duties. Apparently, yes, the car will be mind-controlled. Somehow. If this were intended for real-world use, it would go far beyond the autonomous-driving programs that have been in the works for the past couple of years. Nissan has been real active in that area, with chief Carlos Ghosn saying earlier this year that a "hands-free" car for heavy stop-and-go traffic may be available within the next couple of years. And last year, Google unveiled its autonomous car prototype (though it wasn't nearly as cool-looking as the Bimmer i3) while Tesla Motors has been making noise in that area as well. Besides the i3, MoneySuperMarket has developed the Epic Mind Drive mobile game that uses face-tracking technology to control a car on the screen. The idea with these two whiz-bang ideas is to get drivers to realize that they should think as they drive, it seems. As for the telepathic i3, we're as interested in details as the next website, so we checked out the two videos that are supposed to hype the project. While there is some groovy jazzy-electro music involved, the details of how this works are pretty much nonexistent (16 sensors, think to turn the wheel, and that's about it), so we look forward to hearing more about the project once it's underway.
