Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

2016 April Fools' Day: Morgan digs at Tesla, Mini's scissor doors, more

Every year automakers go out of their way to come up with gags for April Fools' Day. Sometimes the jokes fall flat, but occasionally a company really nails it with an idea that we'd actually love to see. Rather than scouring the Web for all of these stunts, you can find some of our favorites right here. Morgan MOGrod The Morgan Motor Company's MOGrod is one of our favorite April Fools' jokes so far this year because it's a car we wish could be real. The company says on Twitter that the retro hot rod uses a 3.7-liter Ford V6, and there are already 250,000 preorders, which is a play on the huge number of reservations for the Tesla Model 3. Morgan took the joke even further by sketching a landspeed record version for the Bonneville Salt Flats. Mini Scissor Doors The people at Mini apparently have a lot of free time because the company has two gags this year. The first is the scissor door option. The idea cleverly plays on the myriad ways customers can customize their Mini, but this solution doesn't look like anyone could easily enter the car due to the way these doors open. Mini Hipster Hatch There's also the Hipster Mini, which is a much funnier idea. This fictional hatchback would be perfect for fashionable Millennials thanks to features like Instagram-filter windows and a fixed-gear drivetrain, which limits the top speed to 25 miles per hour. The interior uses stonewash denim upholstery and packs a twin-deck cassette player. Skoda Dog Umbrella People love dogs, and owners know that a wet canine can be a mess. Skoda is ready to tackle this problem with an umbrella for your mutt. Made from unobtainium, the gadget hides in the door when not in use, but when raindrops start falling, people can keep their pup dry. Skoda Snowman Skoda's Facebook page also teases us with a very cool vehicle. The Snowman is a 396-horsepower plug-in hybrid snow machine. With its tracks, the company's newest model would never have to worry about getting stuck in the winter. Opel Adam C Sure, electricity and hydrogen are cleaner forms of fuel than gasoline or diesel, but Opel has a way to make your car even more environmentally friendly – muscle power. Wind up the crank at the rear for 15 minutes, and the Opel Adam C is good for 125 miles. GM's European division also claims that owners get a great workout because a full winding session burns 400 calories. You wouldn't feel guilty about picking up that pizza after cranking up this hatchback.

Evo blasts around in a Spa 24H-winning Mazda RX-7

Think of the Mazda RX-7 today, and your thoughts likely turn to the turbocharged third-generation version of the '90s that's an icon among the tuning and drifting communities. Many years before that swoopy coupe was hanging the tail out, the first model of RX-7 was also quite a track star, though. Evo's Richard Meaden has gotten ahold of a race-prepped version that counts a victory in the 1981 Spa 24 Hours to its name – the first Japanese car to claim that honor – for a fantastic video. With 225 horsepower and weighing around 1,984 pounds, this RX-7 doesn't look like a giant killer on paper. However as Meaden illustrates, the coupe puts those rotary-powered ponies to very good use. Driving it requires constantly keeping things on the boil because the muscle is essentially absent below 7,000 rpm. Once in the sweet spot, things start progressing quickly, though. As a wonderful cap to the wall of noise from the engine, little licks of flame also shoot out of the exhaust on downshifts. Thankfully, Evo's video team captures all of the mechanical noises quite well, and the clip is a treat for those with a good pair of headphones. Despite the race-winning pedigree, Meaden has no problem grabbing the little coupe by the scruff of the neck. He chucks it through the corners to get the tail loose, and the little wisps of smoke from the rear tires prove the original RX-7 knows how to drift too. These early cars definitely worth being remembered in the pantheon of Mazda performance.
