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.

2016 BMW M3 gains new colors, LED taillights

The BMW 3 Series gets a few new models and some significant mechanical tweaks for its recently announced 2016 refresh. At the same time, the Bavarian brand is taking the opportunity to make some much more minor adjustments to the M3, too. BMW didn't mention the M3's changes in its announcement of the 3 Series refresh, but company spokesperson Hector Arellano-Belloc explained the updates to Autoblog. On the outside, the sport sedan now comes with full LED taillights, and the exterior is available with new colors from BMW Individual: Smoked Topaz Metallic and Champagne Quartz Metallic. The shades join Tanzanite Blue Metallic and Azurite Black Metallic from the brand's bespoke division. Under the hood, everything is the same with a twin-turbo, 3.0-liter inline-six engine making 425 horsepower and 406 pound-feet of torque. Inside, the M3 gains the improved navigation system from the 3 Series that features over-the-air map upgrades. There's more chrome trim around the interior, as well. "Given how new it is, the changes to the M3 are minimal," said Arellano-Belloc to Autoblog. However, the tweaks show that BMW is trying to keep the performance sedan at the top of its game.

BMW 8 Series coming in 2020

As good as the BMW 7 Series may be – and trust us when we say it is very good indeed – it just can't compete with the marketplace juggernaut that is the Mercedes-Benz S-Class, at least not where global sales are concerned. And with sales come profits, especially at the six-digit price point many of these high-end luxury cars sell for. Put simply, Mercedes is cashing in on the S-Class, and BMW wants a bigger piece of that pie. It comes as little surprise, then, that Autocar reports BMW is currently considering two proposals for a new 8 Series that would slot just above its current 7 Series. One option is the currently-en-vogue four-door coupe. The other option is a more traditional two-door coupe, likely with a cabriolet option. The last time we heard such rumors, BMW was dismissing them back in 2013. Whichever way BMW decides to take its 8 Series plans, Autocar suggests that a concept vehicle ought to hit the show circuit in sometime in 2018, with a production model following in 2020. The car would be based on the underpinnings of the latest 7 Series, with a price considerably less than the Rolls-Royce Ghost (which also falls under the BMW umbrella). Considering BMW's penchant for multiple model variants, we won't be surprised if all three options get the green light, with a Gran Coupe version standing as the flagship. With the 6 Series Gran Coupe currently priced just below the 7 Series (and at a hefty premium to a comparable 5 Series four-door), an 8 Series would likely brush up against $100,000 for a base price. That might not take much out of S-Class sales, but it would make some tidy profits for BMW. Related Video:
