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.

BMW M135i vs. Mercedes A45 AMG in Euro small-lux throwdown

BMW and Mercedes-Benz - please, please, please bring the M135i and A45 AMG hatchbacks to North America. For as long as we can remember, buyers in the New World have been forced to look longingly at Europe and Great Britain and the excellent super hatches that are so routinely offered there. And while we're quite content with the Ford Focus ST and Volkswagen GTI, having a 360-horse five-door with a premium, content-rich interior sounds quite nice.
Our envy for Europe has grown after watching the latest video from Drive, which stars Chris Harris, the Mercedes-Benz A45 AMG and the BMW M135i. This latest battle between MB and BMW takes place on both road and track, with Harris providing a running commentary. If you're interested in the upcoming Mercedes CLA45 AMG, you should pay special attention to the section on the A45, as the two are essentially fraternal twins. While the video is a bit on the long side, it provides a comprehensive rundown of both cars, giving those of us in North America just a small taste of what we're missing.

Next-gen BMW M5 spied on Munich roads

BMW is still hard at work developing the next-gen M5 around the company's home base in Munich. Unfortunately, the Bavarians are keeping the super sedan plastered with camouflage, which makes picking out the details rather difficult. There are some tiny tweaks from the previous spy shots, though. Obviously, these are still early development vehicles, so it's hard to know whether these changes are in any way meaningful. Up front, this M5 still has an air intake stretching all the way across the lower portion of the bumper. The earlier shots showed this piece with a uniform width, but the designers added a little flair this time by lifting the center portion slightly for a more attractive look. Comparing the two examples in profile, the suspension has seemingly been lowered on the latest one to tuck the tires closer to the fender lips. Most parts have carried over, though, including the massive, cross-drilled brake rotors and quad exhaust tips poking out from the rear. The next M5 should have no problem backing up its mean looks, though. All indications, including earlier spy shots, suggest that the high-performance sedan will gain all-wheel drive, at least as an option, and power will be around 600 horsepower. While about the same as the current 30th anniversary edition, the future 5 Series will reportedly follow the lead of the latest 7 Series by going on a big diet thanks in part from a new, lighter platform.
