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.

Editors' Picks June 2023: BMW 3 Series and more luxury sport sedans

This month sees a number of luxury sport sedans gain Editors' Pick status thanks to updated or recently-all-new models coming out. The BMW 3 Series is a longtime favorite, and so is the Alfa Romeo Giulia at this point. Just like the electric version of the G80, though, the gasoline version is also an Editors' Pick this month. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get an EditorsÂ’ Pick designation. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in May that earned an EditorsÂ’ Pick. 2023 BMW 3 Series 2023 BMW 3 Series View 15 Photos Quick take: The 3 Series may not be the standard anymore, but it's still a superb luxury sport sedan with powerful engines, great handling, impressive tech and tons of space. Score: 7.5 What it competes with: Mercedes-Benz C-Class, Audi A4, Alfa Romeo Giulia, Cadillac CT4, Acura TLX, Lexus IS, Infiniti Q50, Genesis G70, Volvo S60 Pros: Enjoyable and powerful engines; fun handling; lots of space in rear seat and cargo area; attractive design inside and out Cons: Infotainment is frustrating to use sometimes; value isn't the best From the editors: Road Test Editor Zac Palmer — "The 3 Series ticks all the boxes that a top-shelf luxury sport sedan should. It's attractive but not gaudy. The driving dynamics leave me grinning at the end of a fun road, but don't beat me up on the highway. Any and all modern tech is present and accounted for. And while the price is high, it's not so bad for what you get. I'm an especially big fan of the M340i with its inline-six, but the four-cylinder in the 330i is an excellent option if you don't want to spend as much." In-depth analysis: 2023 BMW 3 Series gets fresh styling and infotainment   2023 Genesis G80 2022 Genesis G80 Sport Prestige View 61 Photos Quick take: The G80 has looks to kill, and it backs that design up with a functional and also-gorgeous interior. There's a lot of value to be had with this nice-to-drive luxury sedan.
