Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

Overheated dog rescued from BMW by concerned bystander

Dogs, cars, and summer heat do not mix. Hundreds of dogs fall ill and die each year from heat exhaustion when left in cars on hot days, according to the American Veterinary Medical Association. In Grand Bend, ON, a passerby rescued a small dog from such a fate when he smashed out the rear window of a car and pulled the dog to safety. According to CTV, two unnamed individuals attended a festival on Saturday, June 11 celebrating the unveiling of a new band shell in Grand Bend. They allegedly left their small dog locked in their car in a parking lot. Temperatures across Ontario on June 11 approached 90 degrees Fahrenheit, and even with the windows cracked and the sunroof open, the dog was in obvious distress. Will Costa was also attending the festival when he heard an announcement over park loudspeakers calling for the owners to report to the parking lot to rescue their dog. "When I heard the announcer, I couldn't believe it," Costa told CTV. "It was so hot." Costa and a few other festival attendees moved to the parking lot to see what was happening, and saw a small crowd surrounding a man attacking a BMW with a large rock. After twenty minutes of work, the man with the rock finally shattered the BMW's passenger rear window and retrieved the suffering dog. The owners didn't show up for nearly another hour. "The dog was completely soaked," said Costa. "The owners didn't show up for another fifty minutes. I believe in another fifty minutes it could have been fatal." The crowd gave the dog water and called the police. Costa told CTV that the owners were confused and embarrassed when they finally arrived, and were told by responding officers to report to the local police station. There is no report yet of warnings issued or charges filed against the owners. Related Video: News Source: CTV, AMVA Auto News Weird Car News BMW Safety Videos heat
