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.

BMW, Mini recall nearly every PHEV model built in 2020 due to fire risk

BMW is recalling a majority of the plug-in hybrid models it built in 2020 because their battery pack poses a fire risk. That's 4,509 vehicles covered by the campaign in the United States, including some made by Mini. The list of cars affected by this voluntary recall includes 2020 and 2021 examples of the 530e, the X3 xDrive30e, and the Mini Countryman SE, coupe and convertible variants of the 2020 i8, as well as the 330e (pictured), the 745Le xDrive, and the X5 xDrive45e from the 2021 model year. All are equipped with a lithium-ion battery pack whose cells might have been contaminated by debris during the manufacturing process, according to a recall notice issued by the National Highway Traffic Safety Administration (NHTSA). BMW hasn't revealed what exactly found its way into the Samsung-built battery pack's cells, or how, but it pointed out the debris can cause a short-circuit, which increases the risk of fires and injuries. It added that it became aware of the problem after four gasoline-electric X5s experienced what it refers to as a thermal incident.  Engineers are currently developing a remedy to the problem. Until a solution is found, BMW is asking owners of affected cars not to charge the battery pack, not to drive in manual mode, not to engage sport mode, and not to use the shift paddles. It expects to begin fixing cars affected by the recall on November 23, 2020. 26,700 cars manufactured between January 20 and September 28, 2020, are part of the recall globally. Outside of the United States, BMW also sells plug-in variants of the X1, the X2, and the 2 Series Active Tourer. It has been a bad month for electrified cars. Ford delayed its Escape PHEV after a recall of its Kuga twin in Europe over fire risk. U.S. safety officials are reviewing reports of fires in the Chevy Bolt EV, and Hyundai has expanded a recall of the Kona EV.

This Alpina C1 is a rare bit of BMW 3 Series history

Over its five decades in the business, German tuner-turned-automaker Alpina has established a long history of taking great BMWs and making them just a bit tastier, more luxurious, and well... faster. Of course, they haven't always been the land rockets of modern day, however that's not to say they were exactly tame. Back in the early 1980s, this was one of the cars to have—an Alpina C1 2.3. Based on the original E21 BMW 3-series, the C1 2.3 bridged the performance gap between the standard BMW 323i and Alpina's hard-charging B6 2.8. It summoned up a heady 170 horsepower and disposed of the 60 mph sprint in just seven and a half seconds. Not shabby at all. 33 years later, this '83 Alpina C1 is back up for sale , and it's still quite the head-turner. RELATED: Check Out the Hard-Charging 2016 Alpina B6 xDrive A look back at the C1's contemporary relatives show just how wide Alpina's performance gap had been. Introduced in 1977, the BMW 323i offered up 141 horsepower courtesy of BMW's famed M20 straight-six engine, a big performance improvement over the E21's previous four-cylinders. The Alpina B6 2.8 3-series on the other hand, introduced in 1978, blew its doors off thanks to the bigger 2.8-liter straight-six plucked from the BMW 528i, offering up 200 horsepower. All that, in an early 3-series. With that in mind, a middle-of-the-pack car made sense, so Alpina treated the 323i's straight-six to some of the B6 2.8's goodies, minus the former's Bosch fuel-injection system. Bilstein shocks were part of the diet too, along with oversized disc brakes, sleek alloy wheels, as well as the tell-tale Alpina front splitter, rear spoiler, and racy side-stripes. RELATED: The BMW Isetta is Coming Back, But as an Electric Vehicle! Inside, Alpina added a dose of luxury as well. One could order their C1 2.3 with the gorgeous optional Recaro seats with Alpina stripes, as well as a bespoke leather steering wheel, gear knob, and speedometer. Top speed? About 130 mph. Compared to regular E21 BMW 3-series cars, these are quite rare. How rare is a point of debate, however. Production estimates range from as few as 35 to as many as 400, depending on the source. Regardless, you certainly don't see them everyday, and if this one fits your fancy... it lives in Philadelphia, Pennsylvania. Related Video: This article originally appeared on Boldride.com.
