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.

Welcome Audi RS6 Avant, goodbye Lincoln Continental | Autoblog Podcast #592

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Green, John Beltz Snyder and Assistant Editor Zac Palmer. Our editors cover a lot this week, starting with the news. They geek out over the Audi RS6 Avant coming to America, and mourn the loss of the Lincoln Continental. They address rumors of the Toyota Land Cruiser's demise, and analyze spy photos of the Ford Mach E electric crossover. They also honor the memory of the godfather of spy photography, Jim Dunne. Finally, they talk about driving the BMW Z4, Ram 1500 EcoDiesel, and another diesel, the diesel-powered Mazda CX-5 Skyactiv-D.

British automakers take costly precautions as Brexit 'no deal' fears grow

LONDON — Carmakers in Britain have triggered some Brexit contingency plans, such as certifying models in the EU, and are working on redrawing production schedules and stockpiling more parts to defend against any loss of unfettered trade after Brexit. The moves are aimed at ensuring plants, which rely on the just-in-time delivery of tens of thousands of components, can keep operating after Brexit on March 29, but will add costs and bureaucracy which could risk their long-term viability. London and Brussels hope to agree a deal by the end of the year to avoid tariffs and trade barriers, but Prime Minister Theresa May's proposals have been criticized by both Brexiteers, who want a cleaner break from the bloc, and the European Union. McLaren Automotive is looking at having its cars certified by both a British and an EU agency to smooth sales. It is also planning to stockpile critical components and change shipments into the EU around Brexit if there is disruption. "I will sell a little more in January and February and plan to pick the volume up in May and give us a leaner period through the change point," Chief Executive Mike Flewitt told Reuters. BMW, which said last week it would move the annual summer-time shutdown of its British Mini plant next year to April, is looking for lorry parking areas and warehousing on both sides of the channel and is seeking to sign contracts to lease certain locations, a spokesman said. It is also investing in IT systems to handle any new red tape as carmakers estimate tens of thousands of new documents could be needed if tariffs and customs are imposed. The German carmaker's Brexit plans are costing millions of pounds, a source familiar with the matter told Reuters. But Honda, which builds 10 percent of Britain's 1.67 million cars at its Swindon plant in southern England, is not in the market to buy "huge amounts of warehousing space," its Europe boss Ian Howells told Reuters. "It's been a very precise calculation or estimation of what components need to be brought in," he said, adding the firm could also alter its output to sell more into the EU at the start of next year. Waste of money? Many British carmakers have also asked suppliers to look into how they would handle delays at ports, executives told Reuters, as thousands of parts, engines and finished models move between Britain and the continent every day.
