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.

      So much hate on the Alpina wheels. Other than the pain of having to clean all of those spokes, I think they look phenomenal!

        Yeah, that's one potential problem with those. But those vanes at least look somewhat straight. It's more the subtle bends and nooks and crannies in some wheels that cause the major issues. Plus, who knows, maybe the airflow on those can help deflect some of the brake dust. But who am I kidding. It's probably a PITA to deal with...

      "What do you drive?" "B4." "Before what?" ...sorry.

      Actually I prefer this to the M variants, more subtle. It is just my opinion but the M series has grown more garish through the years. This looks to be fast and competent without all the aggressive body changes.

      Over the last few generations, I've preferred the Alpinas to the Ms. This is no different.

      Love that color. Wheels are a personal preference - I kinda like the Alpina wheels, but that set is just a bit too big for my taste. That relatively small spoiler and new front fascia improve the look over stock too.

      Dear Alpina: it's time to move on from the wheels. They make every car you put them on appear less aggressive.

      21 inch wheels... a little excessive!

      BFD. Dinan regularly pulled 493 out of 3.2L S64 engine, supercharged and intercooled. WITH a BMW warranty. Albeit at $20K plus. The more things change, the more they stay the same.

      Kinda interesting just how big cars are now. But the good news is technologies are allowing for bigger cars that weigh the same or less than their tiny counterparts.

      Slight problem for UK BMW fans, is that the 'M' cars happen to named after our worst congested roads, of which the M4 is one of the worst.

      It looks nice, as do all the new BMW variants. Clean lines. The wheels are also nice. Question: Are the Alpina models totally factory-warrantied cars? Or is the warranty on the performance work ONLY provided by Alpina? They aren't affiliated with BMW, right?

        Look it up. Warranteed through BMW, same as Dinan.

          That's nice. Although, for the premium cost, I guess it should be that way. I know that with Audi, you can get Stasis work done, with a warranty. However, I believe the aftermarket work is covered by Stasis, not Audi. Kind of a big difference.

        Alpinas generally if not always are built in their final form in BMW plants on the assembly line. this allows BMW to offer low volume specialties while not having to stock them as regular models.
