BMW to change model designations, further yet from actual displacement?

Once upon a time, you could look at the back of a trunk lid of a BMW and come up with a pretty fair idea of what sat under its hood. For example, a 320i was a 3 Series with a fuel-injected, 2.0-liter engine, a 328i was a 3 Series with a fuel-injected, 2.8-liter engine and a 328Ci was a two-door 3 Series with the same engine. Those were good days.
Today, though, that simplicity is dead and gone. A 328i now has a 2.0-liter engine, just like the 320i, while the simple "C" designation that was affixed to two-door models has been replaced with a "4," so we have a 428i and a 435i. It gets worse, though. A 550i uses a 4.4-liter, twin-turbocharged V8 (it should be a 544ti, although we'd be willing to hear an argument for "tti") and a 740i uses a 3.0-liter, turbocharged six-cylinder, which is the same engine found in a 535i. It's madness.
And, well, it's about to get madder, if a post on a BMW enthusiast forum is to be believed. According to f30post.com, we could see a shakeup in at least the 3 and 4 Series nomenclature, thanks to an impending refresh that will see the addition of new, turbocharged four- and six-cylinder engines, codenamed B48 and B58, respectively.

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.

Bristol returning under BMW power

BMW has had its hand in reviving once-great British automakers, and now its playing its part in the rebirth of another. That marque is Bristol Cars, the automotive offshoot of the Bristol Aeroplane Company. Bristol hand-made luxury sports cars between 1945 and 2011 when it went belly-up, and ever since there's been an effort to bring it back. That effort is now picking up steam, and is set to launch later this year – marking the 70th anniversary of the marque's founding. It's tentatively known as Project Pinnacle, and while future versions are slated to pack plug-in hybrid power developed in collaboration with Bristol's sister company Frazer-Nash (which is now focused on battery technology), the first new Bristol in a dozen years is slated to pack BMW power. Details accompanying the announcement below are few and far between, but one way or another, it won't be the first time BMW will have played a part in breathing new life into a British automaker. The Bavarian company of course revived Mini, and made Rolls-Royce what it is today, but was also was briefly the custodian of Rover, Land Rover and Bentley, and has been linked to a potential (if unrealized) effort to bring back Triumph. Its role in Bristol's rebirth under Project Pinnacle may be less involved than all of those, but at very least we'll know that the new British GT will have a proper engine under the hood. BRISTOL CARS CONFIRMS POWERTRAIN FOR 70th ANNIVERSARY PROJECT PINNACLE • First new Bristol car in more than a decade to feature BMW powerplant • High performance powertrain earmarks resumption of the history between Bristol, Frazer-Nash and BMW dating back to 1930s London, England, June 2015 – Iconic British carmaker, Bristol Cars, makes the second in a series of announcements today about its first new car in more than a decade, codenamed Project Pinnacle. Project Pinnacle, which is set for launch later this year, will be a 70th anniversary celebration model, referencing Bristol Cars' rich heritage and executed as a modern take on the best of British craftsmanship, engineered to excite and satisfy as a high performance Bristol car. Bristol Cars is deeply proud to announce that the machinery underpinning this high performance new vehicle will be a BMW powerplant. The result will a sublime British sportscar with characteristics cultured uniquely for the first new Bristol since 2004.
