Our member artists continue to give us potential previews of the 2014 BMW 4 Series with some great digital renders. Harold Wood has put together these speculative preview of the F32 4 Series Coupe, F33 4 Series Convertible, F32 4 Series Alpina B4, and F82 M4 coupe.

Seeing the 2014 M3 Sedan (F80) in the harsh winter of northern Sweden this time of the year for cold weather testing is no surprise. Nor is seeing the prototype at a gas station being refueled.

But, the type of fuel that this F80 M3 test car was being filled with by its driver was certainly surprising. An astute witness captured these images at a gas station in Kode, Sweden, while witnessing the test driver of the M3 refueling the car with E85 ethanol fuel (a blend of 85% ethanol and 15% gasoline).

So, is BMW testing an M3 which is powered by ethanol fuel? Very unlikely. Human error seems to be the cause as the witness described the seemingly confused test driver first grab the wrong … CONTINUED

The Stig drives the BMW F10 M5 against Jeremy Clarkson and James May in their American luxury classic cars in an entertaining segment from the Top Gear’s The Worst Car In the History of the World special.

The new BMW M3 (F80) sedan will arrive in 2014, but what should it be like? Steve Sutcliffe puts three of its predecessors through their paces at Brands Hatch to find the perfect ingredients.

The IND F10 M5 engine bay gets a carbon fiber makeover with the GruppeM Ram Air Intake System. Not only does it look the part, but in previous tests by Studie Japan, this carbon fiber air intake system recorded peak gains of +15 HP and +30 lb-ft torque over stock.

On the GruppeM intake for the BMW F10 M5, the factory ductwork and airboxes are replaced with heat-shielding carbon fiber with enhanced inlets to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Of course, reliability is never sacrificed. High-efficiency, high-flow K&N air filter materials prevent contaminants from interfering with proper engine function.

The ever persistent rumors of a BMW supercar surfaces again. This time, Automobile claims that a 600+ hp BMW M8 supercar is headed for a 2016 debut (to celebrate BMW’s 100th anniversary).

Although BMW CEO Norbert Reithofer is said to be ambivalent on the idea of a supercar, BMW M President Dr. Friedrich Nitschke remains dogged on the project while getting creative by considering the production of the M8 on the same carbon fiber / aluminum platform as the i8 hybrid electric sports car. This would not only create production economies of scale (less expensive production costs) while also giving the M8 a significant weight advantage over its rivals.

If such a supercar was indeed built, giving it an M8 nameplate shouldn’t pose an issue or conflict. … CONTINUED

G-POWER has posted the first images and preliminary info on its M6 F13 “Bi-Tronik III” upgrade program, featuring:

• G-POWER Bi-Tronik III with 640HP (+80hp increase). Like on their F10 M5, the G-Power tune ups boost while managing fuel and ignition parameters, as well as managing torque figures during the shifting process for reduced stress on transmission.

• G-POWER coilover suspension RS

• G-POWER SILVERSTONE RS wheels 21″

• (optional) G-POWER Carbon braking system for front axle (likely up to 396mm discs)

• (optional) G-POWER titanium exhaust system with 4-trim titanium/carbon tail pipes

These upgrades mirror the company’s Bi-Tronik III F10 M5 package [full details], which likely means that the M6 … CONTINUED
