Mazda Hazumi concept gets punchy, comes out of its corner early

The official images Mazda Hazumi concept, which previews the next-generation Mazda2, have leaked out from Chinese website Auto.sohu.com ahead of its debut at the 2014 Geneva Motor Show.
The subcompact, four-door hatchback shows off Mazda's Kodo design language in its smallest size yet. Hazumi means "bound" or "spring up" in Japanese, and it is meant to look like it is packed with energy. It is a very attractive little concept and hopefully points to a more stylish face for the next-generation Mazda2.
Mazda has not unveiled the full details about the concept yet, but in a previous release, it said for the car is using a 1.5-liter Skyactiv-D diesel engine. While Mazda has not officially said that the Hazumi shows the next Mazda2, it did say in its earlier release that it "points the way to the future" for the brand's small cars. Reading between the lines isn't too difficult, then.

Mazda RX-3 restomod makes Leno scream, us cheer

The Mazda RX-3 Savanna was the rotary-engined version of the Mazda 808 Grand Familia. Sold in the US from 1971 to 1978, the little Japanese fastback earned a reputation as an excellent racecar, winning events all over the world. A racing connection is how a fantastic 1973 restomod example owned by Savant Young made its way to Jay Leno's Garage. Young said that when he was a boy his uncle used to street race an RX-3, and Young liked how the RX-3 sounded and the fact that a tiny import could go up against and beat big V8s of the time. Leno admitted that he has no connection to the RX-3, saying it's not the kind of car he typically likes. But he liked Young's custom update so much that when he saw the coupe sitting outside the Petersen Museum in Los Angeles, he waited for the owner to show up. Young's changes over the 15 years he's owned the car include dropping in the rotary engine and running gear from the second-generation Mazda RX-7, bridge-ported and methane injected. At 15 pounds of boost he says it's putting out about 400 horsepower. The rear end comes from a Toyota Hilux half-ton pickup, to help put all that power down in a car that weighs maybe 2,100 pounds. The color is taken from the Lamborghini palette. Disc brakes all around, 14-inchers up front, control the velocity. Nothing controls the gas mileage, said to be "maybe 12 mpg." And nothing could stop Leno from whooping it up during the driver. Check out the fun in the video above.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:
