BMW i8 Spyder gets production nod

BMW could be poised to expand its i8 range, beyond the hardtop version of the plug-in hybrid supercar. A report from Bimmerpost is claiming that the i8 Spyder, which we showed you in concept form at the 2012 Beijing Motor Show, will be heading to production.
The website claims the open-roof fuel-sipper was shown to BMW management last Friday as a production-intent model. Other than that, there's not a lot to tell here. The i8 Spyder should feature all the same mechanical and aesthetic features found on the i8 Coupe, just without the confining nature of a roof. It's unclear when we'll see a production i8 droptop make its debut, although this certainly strikes us as the kind of car that should arrive at the Geneva Motor Show.
While an i8 Spyder does seem like a logical leap for BMW's i sub-brand, we're going to keep this one filed under the rumors category until we hear more.

BMW could expand 'i' lineup

Well, this isn't exactly a surprise. BMW CEO Harald Krueger (shown above) has hinted that the i3 electric car and the i8 plug-in supercar could soon be blessed with a bouncing brother, perhaps in the form of the oft-rumored i5. Specifically, Krueger told Frankfurter Allgemeine Sonntagszeitung (as reported by Automotive News) that there was certainly room in the middle of the i sub-brand's current two-model lineup "from the number point of view." The exec declined to offer any additional information. Unlike the i3 and i8, which are their own unique products independent of the rest of the BMW range, the i5 will allegedly be based on 5 Series sedan. It would also eschew the all-electric approach of the i3 in favor of a new and different version of the plug-in hybrid powertrain used in the i8. Rather than that car's turbocharged, three-cylinder gas engine, 129-horsepower electric motor, and 357 total system hp, the rumored i5 – according to our most recent report – would be significantly more powerful. There are rumblings that the new model would have anywhere from 544 hp to 640 hp, with at least two electric motors (one on each axle, making it effectively all-wheel drive). On top of the high performance, the i5 will have no issue running on EV power. According to one report, there'd be up to 78 miles of electric range, and would run purely on electricity up to 36 miles per hour. Even then, the gas engine would only join the party when under hard throttle. What do you think? Will BMW come out with a four-door PHV that could potentially outrun the current M5?

BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.
