2015 BMW 740Ld xDrive

When it first came stateside in 1978, choosing a BMW 7 Series was a simple process. With one engine and one wheelbase, you could just pick what color you want and be on your merry way. Today there are ten different models, forcing drivers to choose among four engines (plus a hybrid), rear- or all-wheel-drive, and two different wheelbase lengths. As if this isn't tricky enough, the options list has more custom choices than the Taco Bell app. Do you want standard paint and upholstery, or something from the pricey BMW Individual collection? What about the headlights: Do you want LEDs, or are the standard xenons just fine? Need a head-up display? Night vision? Adaptive dampers? The list goes on and on. After a week with a new version of BMW's flagship sedan, we've sorted out which model you actually want, although it's still up to you whether or not to order a ceramic-glazed iDrive knob. Our favorite 7 Series is now the 740Ld Xdrive, a conclusion we came to after a week at the helm of the smooth, torquey land yacht. Driving Notes When the diesel 7 first arrived at the 2014 Chicago Auto Show, its engine was already familiar to American consumers. It's the same 3.0-liter, turbodiesel inline-six found in everything from the E90 3 Series to the past two generations of X5, as well as the current 5 Series. A robust 413 pound-feet of torque lathered across the rev range, with peak twist available between 1,500 and 3,000 rpm, and the corresponding horsepower tops out at 255. 0Í–60 happens in a sedate 6.1 seconds, and for those with autobahn dreams the top speed is a modest 130 mph. While those figures aren't terribly impressive, as is often the case with diesels, the real-world application of the engine's power is far more dramatic. Even small throttle inputs produce a smooth surge of acceleration, making the 740Ld feel a lot quicker than the performance metrics might indicate. Even with the current cheap price of gas, the superior fuel efficiency of a diesel engine is worth noting, especially as this model only costs $1500 more than a 740Li xDrive. The diesel tips the scales at nearly 4,700 pounds, yet it boasts a 31-mile-per-gallon highway rating. It's rated at 23 mpg in the city, while our real-world testing saw returns in the mid-to-high 20s. Simple anecdotes about acceleration and fuel economy figures only convey a small part of the 740Ld's goodness.

2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

This BMW i8 gains Alpina V8 power thanks to tuner

German engineering firm Gabura Racing Technologies will strip out everything that makes a BMW i8 green in an effort to create a much wilder machine. Rather than a plug-in hybrid with a turbocharged three-cylinder, the company will cram in a twin-turbo V8. The firm even intends to produce a limited run of these insane conversions for customers. Gabura hasn't actually built one of these beasts yet, but it provided several glimpses of how it would work at the 2015 Professional MotorSport World Expo in Cologne, Germany. The company stuffs the engine under the front end in what looks like a quite snug fit. In several of the photos, the top of the valve covers even appears to be above the base of the windshield. According to BBC Autos, this mill is the S63 4.4-liter turbocharged V8 from the M5 and M6. Additional tuning with some help from Alpina allegedly pushes output to around 760 horsepower – more than double the i8's stock figure. One of Gabura's own six-speed sequential gearboxes reportedly transfers the power to the wheels. Gabura recently posted on Facebook that the engineers are now ready for the first conversion. They promised to "completely rebuild it inside-out, fueled with racing technology." We're very curious to see how an i8 looks and sounds after such a significant transformation.
