Fiat version of Mazda MX-5 Miata to be called 124 Spider

Fiat has a definite use for its recent US trademark on the 124 Spider name, and it's something that should make many performance fans quite happy. FCA CEO Sergio Marchionne confirmed to Auto Express that the Italian brand's future roadster would bear the classic name. Auto Express reportedly asked Marchionne directly about the convertible at the 2015 Geneva Motor Show. The CEO said: "Do we want to do it now?" After another executive verified the name, Marchionne responded: "There you go – a world class premiere right in this room!" Autoblog reached out to Fiat Brand communications boss in the US Ariel Gavilan for more information, and he verified the story. Gavilan said that brand head Olivier Francois confirmed the 124 Spider name to international media during a briefing in Geneva. FCA isn't going quite so far as officially confirming that the 124 Spider shares a platform with the latest Mazda MX-5 Miata, but that's almost a certainty. The two automakers jointly developed the chassis, and the original plan was for it to underpin an Alfa Romeo. However, Marchionne didn't want an Alfa assembled outside of Italy. Fiat even hinted at this possible change as far back as the corporation's five-year plan last summer. Insiders tell Auto Express that the 124 Spider reportedly carries retro-inspired style, and hopefully, that means the roadster evokes the look of the original 124 Sport Spider (pictured above) by Pininfarina. Fiat allegedly is also aiming for a weight less than 2,205 pounds, and the engine range is likely comprised of versions of the brand's 1.4-liter turbo. The mill already pumps out 160 horsepower and 183 pound-feet of torque in the Fiat 500 Abarth in the US. According to Auto Express, Fiat and Mazda have an agreement to launch the Miata in 2015 and the 124 Spider in 2016. A hotter Abarth version could come along eventually, too. Related Video:

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:
