BMW i8's three-cylinder sounds like it's shaping up quite nicely

We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.
Judging by the lovely noise coming from the engine compartment of the i8 in the video, BMW's expertise in tuning high-strung, small-bore engines - remember, BMW Motorrad has quite the penchant for well-conceived motorcycle engines - has come through loud and clear. Now, it's worth mentioning that BMW's controversial Active Sound technology will be included with the i8, so the production car may not sound exactly like this version, which is running with the tech disabled. Owners won't have the ability to disable Active Sound on production i8s.
In related news, Bimmerpost reports that BMW will equip the i8 with an external Active Sound Design system to go along with its Pedestrian Protection System. That means those on the outside will likely hear piped engine recordings from the rear and a sort of "howl" from the front in order to warn pedestrians that the otherwise quiet (when running on electricity, that is) car is approaching. It will also feature technology that can stop the car before contacting a pedestrian.

Acura TLX Type S vs. BMW M340i xDrive | Sport sedan comparison test

Luxury sport sedans are still turning up on the market, and the Acura TLX Type S is one of the freshest cuts of meat in the window. It’s AcuraÂ’s big return to Type S performance models. Benchmarked against the proverbial best performance sedans of the segment, Acura is aiming to not just to compete, but to win dogfights like these. To see if the return of Type S is all itÂ’s cracked up to be, we decided to pin it up against the historical king of sport sedan shootouts: a BMW 3 Series. Specifically, the Type S is taking on the M340i xDrive, which is this AcuraÂ’s most natural competitor from Munich. Should the diehard BMW driver make the switch to Japanese performance? Does Type S do enough to lift this Acura up to best GermanyÂ’s finest? There are a lot of variables at play here, and they all make it complicated to choose a winner. The similarities between these two begin from the top of the spec sheet and go down. Both have 3.0-liter turbocharged six-cylinder engines — BMW arranges its cylinders inline, while Acura chooses a V configuration. Quick-shifting automatic transmissions are standard. BMW uses an eight-speed unit, while Acura uses a 10-speed. Both get electronically-controlled dampers, big brakes and sticky summer rubber. They each offer up usable backseat space and reasonably-sized trunks. WeÂ’d feel just as confident showing up to an important business meeting in either one as we would at a track day. ThatÂ’s the beauty of this mid-tier performance segment. After looking at their specs, it shouldn't be surprising that the M340i is the quicker of the two here. Its 382 horsepower and 368 pound-feet of torque hit noticeably harder from any speed than AcuraÂ’s 355 horses and 354 pound-feet of torque. The Acura is also carrying an extra 232 pounds of curb weight over the Bimmer, which makes the M340iÂ’s 1-second advantage in the 0-60 mph sprint make perfect sense. For the record, BMW quotes a 4.1-second time, and Acura only offers an approximate time of 5 seconds. Both estimates feel accurate. Beyond sheer acceleration, both engines offer up their own version of tingly feel-goods. BMWÂ’s inline-six is as smooth as ever as it plays its sonorous note all the way to the 7,000 rpm redline. There are few sounds in the automotive universe that surpass the glee we feel when listening to a BMW inline-six at full-chat, and that rule still applies to the M340i.

BMW takes 30th Anniversary Edition M5 out to drift

If you only look at the videos from BMW, it appears that the best way to celebrate the 30th birthday of the M5 is some smoky drifting, and it sure looks like a great way to mark the occasion to us. Now that the Bavarian brand's new 30th anniversary special edition is all set to hit the road, the most powerful M5 ever is getting it own chance to roast its tires on video, as well.
The M5 30th Anniversary Edition shouldn't have any problem hanging its rear end out, really. Under the hood, its twin-turbocharged 4.4-liter V8 is turned up to 600 horsepower and 516 pound-feet of torque and can allegedly sprint to 60 miles per hour in a scant 3.7 seconds. That's pretty impressive for any sports car but especially for a sedan that can still carry four passengers comfortably cosseted in leather and Alcantara upholstery.
BMW is making just 300 of these celebratory models worldwide, and appropriately for the anniversary, only 30 of them are going to be available in the US. If the special M5 doesn't make your heart race, the video basks in a little nostalgia, as well, by showing off the original model for some historical context.
