These are KBB's Top Ten Green Cars for 2015

For the second straight year, the Top Ten Green Cars list from KBB (i.e. the acronym for Kelley Blue Book) should have been retitled KBBimmer. That's because the BMW i3 electric vehicle has topped KBB's list of greenest production vehicles for two years running. That means that having the lowest purchase price wasn't that big of a factor in determining the winner. KBB releases its list about this time of year every year in honor of Earth Day and this year not only praised the Bimmer for its performance and single-charge range, but also noted that its factory is powered by wind turbines, which gives the car and the company a few more treehugger points. Meanwhile, KBB didn't exactly surprise a ton of people by including models like the Chevrolet Volt extended-range plug-in (with a caveat that the next-generation version will be coming out next year), Nissan Leaf and Tesla Model S EVs and the Toyota Prius' four hybrid variants. Other somewhat lower-profile advanced-powertrain models to make the cut were the Honda Accord Hybrid, Toyota Camry Hybrid, Volkswagen e-Golf and Ford C-Max Hybrid. Rounding out the list was the Volkswagen Jetta TDI, the only diesel that KBB recommended as a Top Ten pick.

BMW Concept X5 eDrive plug-in hybrid headed to Frankfurt

With six confirmed public debuts scheduled for the upcoming Frankfurt Motor Show, BMW is definitely going to have its hands full. While we've already driven models like the 4 Series and the i3, one of the more interesting introductions is a "concept" plug-in hybrid version of the new F15 BMW X5 called the BMW Concept X5 eDrive.
As the second concept to wear the eDrive name, this X5 combines a 95-horsepower electric motor with a turbocharged four-cylinder engine to balance performance and efficiency. On the green side of things, BMW says that the eDrive system allows the X5 to reach speeds of 75 miles per hour and a range of 19 miles (although we're guessing not at the same time) under electric power only, to go with fuel consumption of about 62 miles per gallon US (3.8 liters per 100 kilometers). For performance, this plug-in can still accelerate from 0-60 in under seven seconds, and drivers can select from three PHEV modes: one that operates the system automatically, an all-electric mode and a Save Battery mode to preserve the battery's current state of charge.
Aside from the obvious plug port on the left front fender, the X5 eDrive is differentiated from the 2014 X5 with slightly restyled front and rear fascias, subtle blue accents tying in with the BMW i line and lightweight, aero-tuned 21-inch alloy wheels. There is no definitive word on whether the Concept X5 eDrive will make it to production, but judging by BMW's recent commitment to plug-in vehicles, we wouldn't be surprised to see an X5 PHEV on the roads within the next couple of years. We'll see the Concept X5 in just a few weeks in Frankfurt, but until then, scroll down for the official press release.

Alpina bringing new B4 Bi-Turbo Cabrio to Geneva

Interested in picking up a new BMW 4 Series with a turbo six? You've got options: you can get the 435i with 300 horsepower or spring for the M4 with 425 hp. But if it's the convertible model you want, we're afraid you'll be limited to the latter as the M division can't help you (at least not for the time being). But that's where Alpina comes in.
The aftermarket tuner closely associated with BMW offers the B4 Bi-Turbo (at least in Europe) with that same 3.0-liter twin-turbo inline-six massaged up to 410 horsepower that starts to pose a threat to the M4. What's more is that the Alpina's 442 pound-feet of torque eclipses the M4's 406 lb-ft, to say nothing of the 435i's 300.
Best of all, Alpina just confirmed via Facebook that it'll offer the B4 in convertible form, bringing the resulting BMW Alpina B4 Bi-Turbo Cabrio to the Geneva Motor Show. We'd expect the weight penalty to knock it slightly off the coupe's quoted 4.1-second 0-60 time, but not by much. If only BMW were to bring this one Stateside like it does with the B7 sedan.
