The 2017 Alpina B7 xDrive isn't as cool as the BMW M760i

Steve Ewing is good people, but when it comes to big BMWs, he talks nonsense. He argues, incorrectly, that the new Alpina B7 is somehow cooler than the new M760i. Here's why he's wrong. No surprise, but the bulk of the pro-M760i argument comes from under the hood. Yes, both cars produce 600 horsepower and 590 pound-feet of torque, but it's where the power comes from that really matters. The M760i's power is just much more accessible, with peak torque coming in at just 1,500 rpm, while the Alpina makes owners wait until 3,000 rpm for max twist (a fact Ewing glosses over). The V12 also offers up all 600 horsepower at 5,500 rpm, 250 rpm earlier. Sure, the Alpina is 0.3 seconds faster to 60 miles per hour – it does the deed in 3.6 seconds to the M760's 3.9 seconds – but it relies on a tweaked transmission setup to do it. Not only that, but big automakers like BMW are usually quite conservative about performance figures, so it's still a bit early to hand a medal to the aftermarket. Here's the other thing about the engines – Nigel Tufnel would prefer the M760i. See, the Alpina has a 4.4-liter, twin-turbo V8, but the M760i has a 6.6-liter, twin-turbo V12. To paraphrase Tufnel, "This one has a V12." We rest our case. Other changes between the two cars are largely in the eye of the beholder – we can talk about the transmission, suspension, and xDrive changes until we're blue in the face, but we simply don't have enough information about the two setups to make substantive arguments – some people might prefer the subtler styling of the M760i. We're not going to blame anyone for liking the more aggressive look of the Alpina, with its big, quad-tipped exhaust, meaty front splitter, or aggressive side sills. And those 21-inch Alpina wheels? Easily the coolest styling detail. You can get a closer look at them, and the Alpina's other changes, in our live gallery from the floor of the Geneva Motor Show.

BMW i8 will be first production car to use Gorilla Glass

What do smartphones and the BMW i8 have in common? Glass. Scratch-resistant Gorilla Glass, that is. The i8 will be the first production car to use the chemically hardened material, which is more durable, lighter and provides more sound deadening than conventional laminated automotive glass. We thought it would be a natural replacement for windshields, but, according to Autoweek, BMW said it will be used for the rear window for sound deadening purposes. The Gorilla Glass will still be laminated, with two 0.7mm thick layers of it sandwiching an acoustic sheet, reports Autoevolution.
BMW reportedly claims the i8 will weigh less than 3,285 pounds, and to offset the heavy hybrid powertrain to reach that goal the automaker has implemented lightweight materials normally not found in mass-production automobiles. With a carbon fiber reinforced plastic (CFRP) monocoque used for both the (relatively) pedestrian i3 and the upscale i8, it's not surprising BMW was also the first to jump onto Gorilla Glass, especially given the timing of a report that a high-end automaker would introduce it within the year.

BMW 1 Series prototype packs direct water injection

Just a few months ago, BMW showcased an M4 that was modified to serve as the safety car for the MotoGP racing series. The flashing lights and emergency equipment, however, weren't the only modifications BMW made to the performance coupe. It also packed an innovative new water injection system. And now it's furthering the development of that system by running it in a 1 Series hatchback as well. Revealed at the BMW Group Innovation Days 2015 event, this five-door 1 Series packs a three-cylinder gasoline engine – like the one found in a Mini or i8 – but fitted with the direct water injection system. In this application, the system sprays a fine mist of water – yep, regular old H2O – right into the combustion chamber. While mixing water with gasoline normally wouldn't be recommended, in this case it evaporates immediately and helps cool the engine from the inside, allowing it to run at higher efficiency. That cooler running engine brings with it several benefits. It delivers improved fuel economy and lower emissions, to start. It also allows for an earlier ignition point, higher compression ratio, and higher boost pressure in turbocharged engines, delivering increased output. It even cuts down on engine knocking (where combustion occurs spontaneously), reduces wear and tear on the engine, and makes better use of lower octane levels. If that sounds like a win-win-win... win (we're losing count of all the wins here), it's because BMW just may be on to something. Of course it does require a water tank to be fitted on board, which means added weight, but instead of requiring the driver fill up the water tank, BMW has fitted this prototype with a system that replenishes the water level from the air conditioning system when the vehicle is switched off. So unless it's being driven in a particularly extreme climate, it doesn't even need topping up. Add one more "win" to the list, then. Extra power, improved real-world fuel economy: Direct water injection enhances efficiency. With direct water injection for turbocharged petrol engines, the BMW Group has again succeeded in enhancing the capabilities of conventional engine technology through an ongoing process of refinement and improvement. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at or near full throttle, while at the same time reducing fuel consumption and emissions.
