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.

Volvo, Kia and BYD duke it out in the finals for World Car of 2024

Three electric vehicles — none produced by an American manufacturer — will compete next month for the title of 2024 World Car of the Year, it was announced Monday. The finalists are the Kia EV9, the Volvo EX30 and the BYD Seal (shown above). The latter two are built in China. The three top finalists in five other categories were also named at the Geneva Motor Show in Switzerland. The winners in all six categories will be revealed live during an awards ceremony at the New York International Auto Show on March 27. This year marks the 20th year of the World Car Awards and the partnership with the New York show. Besides car of the year, the other finalists are: Electric vehicle: BMW i5, Kia EV9, Volvo EX30; Luxury car: BMW 5 Series/i5, Mercedes Benz E-Class, Mercedes Benz EQE SUV; Performance car: BMW M2, BMW XM, Hyundai Ionia 5 N; Urban car: BYD Dolphin, Lexus LBX, Volvo EX30; World Car Design: Ford Bronco, Ferrari Purosangue, Toyota Prius. Only Ford among U.S. companies has an entry in the final selections, and only in one category, design, for the Bronco. BMW has four vehicles in the finals, Volvo has three, Kia and Mercedes have two each. BYD from China has two entries as well. The Seal went on sale in in its home market in 2022 and is now available in most of the rest of the world. The BYD Co. (which stands for Build Your Dreams) has surpassed Tesla to become the worldÂ’s biggest maker of electric vehicles, and has its sights set on the U.S. The selection process for World Cars involves 100-plus automotive journalists from 29 countries who vote, as they review and test-drive the eligible vehicles for the 2024 awards. Their journey is captured virtually on World Car TV. Design/Style Geneva Motor Show BMW Ferrari Ford Hyundai Kia Lexus Mercedes-Benz Toyota Volvo Best Cars World Car of the Year

BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.
