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.

These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.
