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.

BMW, Toyota warn about Chinese market slowing down

BMW and Toyota are the latest automakers to become concerned about the closing throttle on the once rapidly accelerating vehicle market in China. There might be drastic effects on their ledgers at the end of the year. With the Chinese stock market no longer looking so healthy, the people just aren't buying as many new cars as in the past. Things got really bad in June after the first drop in deliveries in two years. BMW has already reduced Chinese production by 16,000 units so far this year. Despite the slowdown, the company has kept a brave face. "We experience that volatility in all emerging markets," BMW CEO Harald Krueger said in a conference call, according to Automotive News. The problem for Toyota is a bit stranger. Through July, the automaker's Chinese deliveries were actually up 12 percent. However, the gain was offset by falling sales prices. "This is making our business in China quite difficult. The business environment is getting tougher," Toyota Managing Officer Tetsuya Otake said, Automotive News reported. Much of the weakness in China has come in the middle part of the year, and from January through June deliveries were still up 8.4 percent. This means the effects haven't hit the financial results of some automakers too hard quite yet. In the second quarter, General Motors referenced the "challenging conditions" there but still posted a growing net income of $1.1 billion. Despite falling global sales, Toyota managed record income for the quarter, too.

BMW shows off 435i Coupe with M Performance parts

Greetings from the famous Circuito do Estoril racetrack in Portugal. We're here to put the 2014 BMW 4 Series coupe through its paces, and we'll have the chance to sample the updated 2014 BMW M5 with its new Competition Pack, as well. But before going out for some hot laps, we took a few minutes to check out this 435i Coupe that's been fitted with a full suite of goodies from the BMW M Performance parts catalog.
Starting with the exterior, carbon fiber bits are the most noticeable additions, with the lightweight material added in the form of a massive front splitter, mirror caps and a rear spoiler. Other visual changes include lightweight 20-inch wheels, a blacked-out grille, and unique M Performance side stripes. No, that's not a shadow you see under the 435i's strong side character line - that's a stripe. Yes, we're serious.
Inside (we couldn't get photos of the interior, sorry!), BMW has added its sport steering wheel with race display, unique M floormats, steel pedals, and a whole mess of carbon fiber and Alcantara trim.
