Next CR-Z to lose hybrid powertrain, go with turbo four

The Honda CR-Z has been treading water for years and has already left the European and Australian markets. Meanwhile, it has hung to life in the US with 3,562 total units sold in 2014. The little coupe looks like it should be a winner, though, as the reinterpretation of the classic CRX for the modern age. Unfortunately, a serious lack of performance to back up the sporty styling lets the model down. Although rumor has it, the CR-Z that drivers keeping asking for could be just a few years away. An anonymous source related to Honda's Tochigi, Japan, development center told Car and Driver that a significantly more potent new generation of the CR-Z is on the way to dealers in 2018 with a possible unveiling in 2017. "The new coupe will be a force to reckon with," the insider said. The new CR-Z would reportedly be slightly larger and would be based on a shortened version of the next-gen Civic's platform. Car and Driver even speculates a possible branding change to become the Civic CR-Z. The most encouraging change for performance fans, though, is the coupe finally ditching the IMA hybrid in this market in favor of the 2.0-liter turbocharged four-cylinder from the European Civic Type R. The engine would allegedly be detuned to around 280 horsepower for this application from the 306 hp in the CTR. The hybrid isn't going away entirely, though. For the Japanese market, the CR-Z would use Honda's 1.5-liter turbocharged four-cylinder with electric assist to make around 200 hp. Until anything official comes out, it might be best to treat all of this tantalizing info with a large grain of salt. Rumors of a future CR-Z using the next-gen Civic platform have circulated since 2013, and there has been speculation about using the CTR engine, too. Related Video:

Hyundai-Kia claims 'greenest' title from Honda, Big Three still big losers

Let's start with the good news. On average, any new car you buy in the US today will be 43 percent cleaner than any average new car in 1998. Here's some more good news, for Korea anyway, Hyundai-Kia has been named the cleanest automaker in the latest study by the Union of Concerned Scientists (UCS), which looked at 2013 model year vehicles sold between October 2012 and September 2013 from the top eight automakers (by volume). The bad news? The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The problem for Ford, General Motors and Chrysler lies in their trucks, which sell well but tend to have pretty bad fuel economy (compared to sedans, at least). The UCS calculates its list by averaging "the per-mile emissions for each light-duty vehicle sold by each automaker" and then factors in "the fuel economy, fuel type, and sales volume of each type of vehicle sold by each automaker" and "the upstream global warming emissions from producing and distributing the fuel used by each vehicle, as well as emissions from the vehicles themselves." That all means that, the more trucks you sell, the worse you're gonna do. Then again, the more trucks you sell with 18 mpg, the more you're helping drivers put CO2 into the air, so the UCS is doing a fair comparison of the things that this study is trying to track. More details on the methodology are available on page six of the study PDF. In case you were wondering (we were), UCS did make sure to use the revised mpg numbers for Hyundai and Kia models that were originally overstated. Hyundai has apologized for and fixed those figures and even with the new, corrected numbers, Hyundai's total emissions are dropping at a rate of about three percent a year, enough for it to take the greenest company title for the first time. In fact, this is the first time that an automaker other than Honda has come out on top in the UCS ranking, which has been released six times now, including the first one in 2000 (which looked at 1998 model year data). In 2010, Honda was almost knocked off the winner's perch by both Hyundai and Toyota, but managed to hold on. Chrysler, on the other hand, came in dead last (again) in the ranking of the top eight automakers, snagging the "dirtiest tailpipe" award once (again). Read the UCS' press release below.

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.
