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.

Mazda Recalling Cars Due To Spider Webs In Engines

It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine. According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations. So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
