Mazda's game plan: Compression ignition, superchargers, EVs — and still fun to drive

Today, Mazda announced its new Sustainable Zoom-Zoom 2030 initiative. Dumb marketingspeak name aside, this is Mazda's general plan to make its cars more efficient while still keeping Mazda's fun-to-drive character. The most notable part of this announcement is Mazda's new Skyactiv-X engines and the addition of EVs and electrified powertrains starting in 2019. As we reported back in January, this new supercharged Skyactiv-X engine family will be the first to use high-compression ignition, or HCCI, rather than traditional spark plugs. Each year, fuel economy and CO2 emissions standards grow ever tighter. Each and every automaker around is looking for ways to improve both factors. Initially, most have chosen to downsize engines and add turbochargers. That's why Mazda's new Skyactiv-X engines are going to be so special. They essentially work like a diesel engine, using extremely high compression to ignite the fuel rather than the flame from a spark plug. Adding a supercharger rather than a turbo retains a smooth and immediate engine response. Look for a 10 to 30 percent increase in torque and a sizable boost in fuel economy. Mazda's engine already have some of the highest compression ratios around, but these new engines will push well into diesel territory. The biggest issue so far with gasoline compression ignition is controlling when the gasoline ignites. Mazda claims to have solved this issue, seamlessly moving from spark to compression ignition. This new plan comes 10 years after the first Sustainable Zoom-Zoom initiative was announced. With Sustainable Zoom-Zoom 2030, Mazda wants to focus on the Earth, society, and people. Together with the new engines, Mazda hopes to create a sustainable future that still involves engaging and fun-to-drive automobiles. First, Mazda wants to consider emissions over the entire life of a car. That means reducing emissions generated while building the car or fueling and charging a car in addition to those released while it's on the road. The goal is to reduce emissions to 50 percent of 2010 levels by 2030, and a 90 percent reduction by 2050. New electrified models will debut in 2019 in markets that have a high ratio of clean energy for power generation. Mazda's focus on society aims to improve safety with the Mazda Proactive Safety philosophy. Like with Skyactiv, this ethos goes far beyond simply improving an engine or adding new active safety technology.

2020 Mazda MX-5 Miata RF Automatic Road Test | Cue the sad trombone

Somewhere in Hiroshima, a parade of nearly finished Miatas glides along a track waiting to receive their beating hearts, the powertrains that'll let them ply their road-carving talents the world over. One – let's call him Fred – is eager to begin his new life as a 2020 Mazda MX-5 Miata, bringing joy to his future owner and just generally being awesome, even if the RF power targa-ish roof that's already been applied to him is a tad dweeby. Visions of hairpins and power slides and expertly executed heal-toe downshifts dance in his head Â… and then it happens. He is given the one thing every new Miata dreads: an automatic transmission. Poor guy. This will not, entirely at least, be yet another diatribe in the ongoing Quixotic campaign to Save the Manuals(!). Automatic transmissions can be quite good and even beneficial in sports cars, especially on the track where removing the need to operate a clutch and expertly execute those heel-toe downshifts lets you better focus on the steering, what the chassis is doing and just going faster. That the computers can shift quicker than you can is another obvious advantage. The trouble with the Miata, and why Fred is now shuffling off the line like George Michael away from the Banana Stand, is that the Mazda six-speed automatic just isn't appropriate for a sports car. The automatics in the rest of Mazda's fleet are actually quite excellent, delivering superior response than rival transmissions, and delivering comparable fuel economy despite possessing fewer gears. However, what works well in a compact crossover like the CX-5 or CX-30 is not necessarily appropriate for a sports car like a Miata. Unlike the dual-clutch transmissions or even some sport-tuned conventional automatics of various performance-oriented cars, this one doesn't downshift adroitly when braking into a corner, anticipating your imminent need to get back on the power. The plastic paddle shifters lack the reassuring, mechanical feel of the best examples, and then don't produce quick-enough reactions from the transmission when up- or downshifting. I found using the shifter itself, which is at least oriented the correct way – with downshift forward and upshift rearward – to ultimately be more rewarding as it has a more involving action to it. Still, it's nothing compared to the solid, snick-snick action of the six-speed manual.

Autoblog editors choose their favorite racecars of all time

If you like cars, there is a good chance that you like racecars. There's something about the science and the art of going faster, of competition, of achievement, that accelerates the hearts of enthusiasts. It doesn't matter the series, the team or the manufacturer – there's something about racing that stirs emotions and lifts spirits. It's that way with many of you, and it's that way with our editors. With that in mind, we offer a list of our favorite racecars of all time. Of course, we'd like to hear some of yours in the comment section below. 1970 Porsche 917 Compared to some of the obscure choices by my colleagues, I feel like the Porsche 917 is almost so obvious a pick as to not be worth mentioning. Still, when coming up with my answer, my mind invariably went back to this classic racer – specifically in its blue-and-orange Gulf livery – while watching Le Mans on DVD and later Blu Ray with my dad. Long, low and curvaceous, few vehicles have ever looked sexier lapping a track than the 917. More than just a pretty face, this beauty had speed, too, thanks to several tunes of flat-12 engines over the course of its racing life. In the early '70s, Porsche was a dominant force throughout sports-car competition, and the 917 (shown above at the 1970 24 Hours of Daytona) was the tip of that spear, including back-to-back victories in the 24 Hours of Le Mans. Largely without dialogue or really much of a traditional plot, Le Mans is like a tone poem of racing goodness. While the 917's importance to motorsports history is undoubtedly fascinating, it's still this cinematic depiction of the Porsche racer that draws me in most, especially with the volume cranked. – Chris Bruce Associate Editor 1964 Mini Cooper S How could everyone not be selecting the 1964 Mini Cooper S piloted by Paddy Hopkirk and Henry Liddon? That car, 33 EJB, took the first of British Motor Corporation's four Monte Carlo Rally wins (it should have been five, but French judges got the British Minis [and Fords] disqualified on a technicality regarding headlights... which its own car, the winning DS, was also in violation of). The tiny red car and its white roof beat out Ford Falcons, Mercedes-Benz 300SEs and scores of Volvos, Volkswagens and Saabs. This, along with the several years of dominance that followed, cemented the idea that not only could the tiny, two-tone Mini be a real performance vehicle, but that family-friendly city cars in general could be fun.
