The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed

The BMW specialists at Alpina know how to exploit a niche when they see one. With the BMW M4 still not technically official, it saw the need for a higher performance four-seat convertible than the 435i 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the Geneva Motor Show.
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).

BMW tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

2021 Acura NSX leads this month's list of discounts

The 2021 Acura NSX is an especially good deal this month. Not only does it carry the torch as the vehicle with the biggest discount measured by the percentage off its sticker price, that discount is also the largest of any vehicle currently sold in the United States when measured in sheer size. Here are the numbers: The average sticker price of all 2021 NSX models sits at $161,040. Buyers are paying an average transaction price of $142,907. That equals a discount of 11.3%, or $18,133 of savings. No other vehicle comes close to that kind of discount, with the next largest being for the 2021 BMW 7 Series. Buyers of that luxury sedan are saving an average of $11,661 for a transaction price of $94,884. There's another sharp dropoff after the BMW. In third place is the 2021 Maserati Quattroporte, which actually kicks off a party of savings at Trident dealers across the United States. The '21 Quattroporte is seeing $7,743 cut off its sticker price for an average transaction of $121,962. After that comes the 2021 Maserati Ghibli, which is averaging $7,394 off for a sign-on-the-dotted-line price of $78,592.
