BMW 1 Series sedan prepares to fight Mercedes CLA, Audi A3

The entry-level premium sedan segment is pretty hot right now, with the Audi A3 and Mercedes-Benz CLA-Class doing well for their respective automakers here in the US. Of course, BMW has its 2 Series, but that's currently only available as a coupe, with a convertible bodystyle forthcoming. That all looks to change, however, as our spies recently caught BMW testing a four-door 1 Series sedan that seems to have the A3 and CLA clear in its sight.
BMW's entry-level four-door is expected to ride on the same front-wheel-drive UKL platform that we recently spied in Mini Countryman form. We're pretty sure this thing will launch under the 1 Series line (odds for sedans and wagons, evens for coupes and convertibles), but it's anyone's guess with BMW - after all, the five-door, front-drive Active Tourer wears a 2 Series nameplate.
Look for the 1 Series sedan to launch sometime in 2016 as a 2017 model. Better late than never in the entry-lux segment, we suppose.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

Alex Zanardi back in the driver's seat with BMW

If there's ever been an inspirational story in the pantheon of motor racing history, surely it's that of Alessandro Zanardi. The Italian driver worked his way up the motor racing ladder, making it into Formula One and winning two CART championships for Chip Ganassi Racing back before the series re-merged into IndyCars. Tragedy struck in 2001 when he lost both his legs in a crash at the Lausitzring in Germany, but rather than accept his fate, Alex pushed on. Fitted with prosthetic limbs, he learned to drive a racing car with hand controls and got back in the driver's seat.
Zanardi drove for BMW in the European Touring Car Championship and then in the World Touring Car Championship that replaced it, landing on the podium several times despite his physical disadvantage. He left racing in 2009 to train for the Paralympics, winning two gold medals in London, but Alex apparently couldn't shake the racing bug. BMW modified one of its M3 DTM racers with hand controls for him to test later that year. And now he's returning to motor racing full time.
BMW has just announced that Zanardi will be driving a Z4 GT3 in the Blancpain Sprint Series, the successor to the FIA GT Series and short-distance counterpart to the Blancpain Endurance Series. The car has been modified with the hand controls the Bavarian automaker's racing department fitted to the aforementioned M3 DTM and will be fielded by the ROAL Motorsport team with which Alex challenged for the European Touring Car Championship last decade.
