Automakers are offering more fuel-efficient cars than ever

Even with gas prices near their lowest point in more than a decade, Americans are still concerned about the fuel economy of their cars. More than 4 in 5 consumers say gas mileage will be an important consideration the next time they go shopping for a vehicle, according to the results of a new survey conducted by the Consumer Federation of America, which were released Monday. That's no surprise, says Jack Gillis, director of public affairs for the nonprofit organization. "Consumers have had a long history with volatile gas prices," he said. Though motorists have saved approximately $12 billion this year at the pump compared to 2015, according to AAA, car shoppers expect gas prices to rise again in the future. The average respondent to CFA's survey predicted a price of $3.50 per gallon within the next five years, a figure in line with projections made by the US Energy Information Administration. When those consumers visit dealerships, they'll have plenty of options. More models than ever are achieving 30 miles per gallon or more, according to CFA's annual analysis released in conjunction with the survey, and 15 of 16 major car companies improved their fuel efficiency on their 2016 model-year offerings. Only Ford backslid year over year, per the report. Researchers say American consumers are now enjoying the widest range of fuel-efficient options ever offered, in every vehicle class. Of 1,094 models on sale in 2016, 13.4 percent achieved more than 30 MPGs, an improvement from 11.7 percent in 2015. At the same time, the percentage of gas guzzlers offered for sale has declined. The percentage of vehicles on the market that get 16 miles per gallon or less has fallen from 6.1 percent to 4 percent, says CFA. "Even if you're in the market for a large pickup or SUV, you'd have to go out of your way to find a true gas guzzler," Gillis said. ""Consumers have had a long history with volatile gas prices." – Jack Gillis These results, the CFA suggests, indicate federal standards that prod automakers to invest in fuel-efficient technology are having the desired effect. Manufacturers are keeping pace with the requirements of the Corporate Average Fuel Economy standards, which mandate carmakers achieve a standard of 52.5 miles per gallon in testing, equivalent to about 40 miles per gallon in on-road performance, by 2025. CFA's report singled out Mazda as setting an exemplary standard.

Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
