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.

Toyota, Mercedes, BMW top automakers included in List of Best Global Brands

Interbrand, a consultancy firm, has published its 13th annual list of the best global brands. Besides seeing some shakeups at the top - Apple and Google unseated Coca-Cola (a company that has dominated the survey since its birth), the 100-item list features 14 automakers, most of which enjoyed double-digit gains in brand value.
Toyota managed to retain its spot as the study's top automaker. It finished the survey in 10th position overall (the same as last year), despite a 17-percent improvement in its brand value, from $29.33 billion to $35.34 billion. Mercedes-Benz, BMW and Honda all made the top 20, at 11th, 12th and 20th place, respectively. Hopping a ways down the list, we come across Volkswagen in 34th place, up from 39th in last year's study, with a brand value of $11.12 billion, a 20-percent improvement over 2012. Ford and Hyundai round out the automakers in the top 50, at 42 and 43.
Porsche made the largest year-over-year gain of any automaker, with its brand value increasing 26 percent to $6.47 billion. Chevrolet meanwhile, cracks the list for the very first time at 89th place. As Interbrand notes, Chevy's inclusion is notable because of the sheer number of vehicles it moves for General Motors and its recent push in developing markets. The final interesting note on this survey is the position of an automaker that takes its name and logo more seriously than perhaps any other - Ferrari. The Italian exotic manufacturer finished 98th out of 100, with just $4.01 billion in brand value, a six-percent improvement over 2012.

Editors' Picks November 2023: Toyota Grand Highlander, Buick Envista and some lovely luxury vehicles

It's been a month since we served you with the full lot of Autoblog Editors' Picks, and that master list is going to continue to grow as more new cars enter the market. For November 2023, we have a trio of SUVs coming in at various sizes and price points including the Buick Envista, Toyota Grand Highlander and Mercedes-Benz GLS. And if you're looking for a convertible sports car, the BMW Z4 is one that should make your shortlist, as it finds its way into this month's of Editors' Picks, as well. In case you missed 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 November that earned an EditorsÂ’ Pick. 2024 Toyota Grand Highlander 2024 Toyota Grand Highlander Limited Hybrid Max View 25 Photos Quick take: The Hybrid Max is the one to get, but the Grand Highlander comes highly recommended for its added space, nicer interior and fuel efficient powertrains. Score: 7 What it competes with: Kia Telluride, Jeep Grand Cherokee L, Chevy Traverse, Honda Pilot, Subaru Ascent, Ford Explorer, Toyota Highlander, Mazda CX-9, Kia Sorento, Buick Enclave, Nissan Pathfinder, VW Atlas, Mazda CX-90 Pros: Two hybrid powertrain options; exceptional cargo space; usable third row; refined and quiet ride. Cons: Expensive for the segment; the lesser hybrid powertrain is noisy and slow. From the editors: Senior Editor, Electric, John Beltz Snyder — "The Grand Highlander is a nice alternative to the standard Highlander for the Toyota faithful for its usable third row. The choice of powertrains is a huge boon, too, whether you want a fuel-sipping hybrid, or solid gas engine or a more robust hybrid with extra performance. YouÂ’re just going to have to pay a little more for it all."
