2016 Mazda MX-5 Miata first engine shot revealed

We've dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car's California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don't have engine specifications, the folks over at Autoweek have scored a nice scoop - the first underhood photos of one of the display cars.
In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles' upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.
The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It's entirely possible that the alleged turbo car was, in fact, a mule for the Miata's Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

Mazda working on lithium-ion batteries to replace lead-acid starter batteries

In the quest for ever better fuel economy, car companies are looking for every single advantage possible, no matter how small. This is evident in everything from active grille shutters to the 48-volt mild-hybrid electric assist systems like that in the new Ram 1500. For Mazda, the latest target for potential efficiency gains is the lowly 12-volt starter battery. The company announced that it is partnering with two other companies, ELIIY Power and Ube Industries, to develop a lithium-ion starter battery that would be used on mainstream models in place of conventional lead-acid units. Mazda plans to have them ready for use by 2021. The advantage here would be that 12-volt lithium-ion batteries would be much smaller and lighter than the lead-acid ones they replace. And lighter cars don't need as much fuel to move around. Plus, as an added benefit, making cars lighter also often makes them faster and better handling. This is why companies such as Lotus and Porsche have offered optional lithium-ion 12-volt batteries for some lightweight sports cars. A potential downside to the use of these batteries is increased cost. Lead-acid batteries from your local parts store will run you between $100 to $150. AGM batteries could be between $200 and $300. As for lithium-ion batteries, Lotus introduced the option on the Evora 400 in 2016, and the option cost $1,690. Odds are that a company such as Mazda won't be absorbing all those costs, meaning that the cost of these future Mazdas could increase with a change from lead-acid to lithium ion. Related Video:

Miata is always the answer, but not always the best one

The Mazda MX-5 Miata is a surprisingly versatile car. Not only is it hilariously fun on back roads and closed courses, it can also be a decent daily driver thanks to its solid gas mileage and usable trunk. But, it doesn't excel in every driving situation. Specifically long trips at high speeds, and those involving canine companions. This weekend, I did a roughly 500-mile round trip to my parents' home in Indiana to pick up my recently adopted dog. The trip was 90-percent highways, and I heard every single mile. Our MX-5 Miata Club has the minimally insulated top also found on the base level trim, and at highway speeds the wind and road noise fills the cabin with a loud, steady roar. This likely won't be a problem for fans of white noise, and it can be overcome by the stereo. However, over a few hundred miles, it starts to get old. The suspension, while superb for carving corners, also gets tiresome. On rough Rust Belt highways, it would become a bit overwhelmed, and the whole car would shiver and shake. On the plus side, nothing squeaked, rattled, or fell off in these instances. There are a few other quirks that show up on long trips. The small pedal box and floor-mounted throttle means that there isn't a particularly comfortable place to rest your right foot when the cruise control is set. Neither the door nor the center console have much padding either, so leaning your knees against them for long periods of time isn't advisable. The good news is that the seat itself was surprisingly comfortable, and never once was I feeling any back pain. Plus, when not using the cruise control, the seating position is great, allowing me to stretch out and relax. When I picked up my four-legged compatriot (a 7-year-old mix of unknown breeds named Ruby, pictured above), things became a tad tight. Standing up, she thoroughly filled the passenger compartment. For reference, she's a little over 50 pounds and stands a little more than 2 feet tall. Much bigger dogs, like my family's coonhound and German shepherd mix, won't really fit. This also made her prone to nearly face-planting on the dashboard anytime the car slowed down. She eventually figured out that simply curling up on the seat bottom was the best choice, and then slept for most of the trip. So it worked out, but I think I may have found the limit of a Miata's dog capacity. Would any of this make me want a Miata less? Certainly not. That is if I had a second car.
