Car and Driver 10Best list cracked by Tesla Model S, BMW 3 Series left off

Car and Driver is keeping new blood pumping into its annual 10Best cars list with three new entries making it on for 2015 and a perennial favorite falling off. Among the biggest shocks this year is that the BMW 3 Series and 4 Series are no longer named, despite years of some portion of that lineup earning a mention. In another surprise, the Tesla Model S (specifically in S 60 trim to fit under the $80,000 cost cap) makes it to the 2015 roster and is the only electrically motivated member of the group. Despite the loss of the 3 Series, BMW isn't entirely shut out this year, because the M235i gets its name on the list. Car and Driver argues that the little coupe feels like a welcome throwback to the E46 chassis M3 of the early 2000s. In addition to the Model S, the final newbie to the annual group is the 2015 Ford Mustang GT. The inclusion of these new members knocks the Audi A6/A7 family and Ford Fiesta ST out from the 2014 rundown. The other seven models carry over from last year, including the Cadillac CTS, Chevrolet Corvette Stingray, Honda Accord, Mazda3, Mazda6, Porsche Boxster/Cayman and Volkswagen Golf/GTI. The 2015 10Best cars list certainly seems to have something for everyone from the hot hatch fan to the family man and even the green car driver, thanks to the addition of the Tesla. Head over to Car and Driver to read its detailed explanations for each vehicle's inclusion, but if you've got a difference of opinion or just really like the list, let us know in Comments.

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:

2018 Mazda CX-5 is the only IIHS Top Safety Pick Plus compact crossover

We've highlighted a number of vehicles tested by the IIHS, and specifically ones that come up just a little short of being lauded with the organization's highest safety rating of Top Safety Pick+. The reason most of these vehicles fall short is sub-par headlights. But this time we have a different story. The 2018 Mazda CX-5 actually snagged the coveted award, and impressively, it's the only small crossover SUV the organization has tested to earn it. The reason of course hinges on headlight performance. In order for a vehicle to get the award, it has to have headlights available that score a "Good" rating, in addition to having stellar crash tests. The award for good lighting and the Top Safety Pick+ only goes to the CX-5 with the optional adaptive lighting system available on all trims (optional on the base Sport). The standard headlights on the Sport model earned the second-highest rating of "Acceptable." The CX-5 also earned a "Good" rating in every crash test, including both small-overlap tests. It earned 5 out of 6 points in forward collision prevention, netting a "Superior" rating. There are many safe options in the small SUV category besides the CX-5, though. The Honda CR-V, Hyundai Tucson, Kia Sportage, Mazda's own CX-3, and Mitsubishi Outlander match the CX-5's straight-"Good" crash test ratings. They all also pick up an additional forward collision point in the collision warning category. The best headlights any of them can offer, though, are just "Acceptable," and the standard headlights can be even worse with "Marginal" or "Poor" ratings.
