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.

Electrify Expo is an all-electrified auto show like the old days

In late July, Autoblog swung by Washington, D.C. to check out the Electrify Expo. Now in its third year of nationwide shows, the Electrify Expo calls itself “North America's largest electric vehicle festival filled with over 1 million square feet of the world's top electric brands.” At every stop, visitors can find out about, crawl around in, drive and ride just about any personal conveyance that uses a battery for propulsion. Truth be told, when the show's PR team reached out to us with an invite, we only considered going after finding out about an area showcasing battery-electric tuner cars. EV tuning is undoubtedly going to be huge—eventually—which got us curious about these early days. We figured weÂ’d brave whatever the rest of the expo was to find out whatÂ’s the equivalent of nitrous for a Tesla. See, the EV event scene is still such that one never knows if theyÂ’ll show up to a mix of science and county fairs with a few cars on display just for truth in advertising, or if theyÂ’ll show up to a parking lot with 26 cars, 10 of them locked, 10 of them homemade, and 6 guarded by promotional hires desperate to tap all your identifying info a tablet before dispensing dubious and superficial information. Which is to say, we didnÂ’t expect much. And that makes us chuffed to report: Electrify Expo is great. We hadnÂ’t been strolling the lot outside the old RFK Stadium for five minutes before thinking, “This feels like an old-school auto show!” The exclamation to that point came from a group of four who cut me off to reach the C40 Recharge in the Volvo booth, one of them exclaiming as if he were the group expert and as if his friends were deaf, “THATÂ’S THE LEAST EXPENSIVE ONE! AND ITÂ’S BEEEE-YOUUUUU-TI-FULLLLLL!” I wasnÂ’t there to judge, I was there for the enthusiasm. Automakers had built small, simple, open booths, parked cars in them, then provided visitors the kind of interactions that will do the most good for anyone wondering about or interested in an EV. We only saw two cars that were off limits, the new Volkswagen ID.Buzz and the Ford F-100 Eluminator. Volvo wouldnÂ’t let me get an espresso from their chic little trailer, either, unless I visited the EX90 Experience trailer first. Otherwise, it was a free-for-all. Tesla had a large booth full of cars. BMW had two i7s open for everyone to sit in, next to the Ford booth with that Eluminator and an unlocked Mustang Mach-E GT and F-150 Lightning showing their cooler-chest-frunk trick.

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)
