Silver Stone Metallic 1990 Mazda Miata Mx5 Convertable Automatic Ac on 2040-cars

Auto blog

Reminder: Come hang out with Autoblog and the 2016 Mazda MX-5 Miata on Tuesday, May 19

Do you love chilidogs, French fries, meeting new friends, and the world's most popular convertible? Do you live in Southeast Michigan? Do you like lists of questions? If you answered "yes" to any but the last of those, we'd like to invite you to a little get-together we're hosting next week. Driving impressions are still under embargo for the US-spec 2016 Mazda MX-5 Miata, but somehow we've conned convinced company PR reps to show the car to you, Joe Public Autoblog Reader. We're enthused about telling you more about the ND Miata, but before we do we'd love to share a Coke and talk about cars. Here's the skinny. A group of Autobloggers will be hanging out at the Athens Coney Island, in Royal Oak, MI, next Tuesday, May 19. We'll have the car on display from 5:00 PM to 8:00 PM, and we'd love to see you. If you're a Miata owner, we'd also love to for you to bring your car along for the party. The more convertibles the better (just be prepared to have your picture taken). Go ahead and set your navi for Athens – 32657 Woodward Ave., Royal Oak, MI 48073 ­– and we'll look forward to seeing you Tuesday. Mazda Geeks unite. Related Video:

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

Midsize Sedan Comparison | Honda Accord vs. Toyota Camry vs. Mazda6

The rumors of the midsize sedan's death have been greatly exaggerated. The 2018 Honda Accord and 2018 Toyota Camry together moved more than 262,000 units through May of this year, which is still a ton of cars. Then again, both are down year-over-year despite being completely, and quite impressively, redesigned for 2018. So yes, the midsize sedan's grip on family transportation is weakening. Ford certainly thinks so, yet this change in consumer preferences comes at a time when the current crop of sedans is sensational. They're bigger and more powerful, yet also more efficient. Safety scores are impeccable. They even look better than ever. So before running out to score one of the bajillion little SUVs flooding the market, why not ponder this trio of midsize sedan all-stars that might actually work better? Over the course of three consecutive weeks we tested the 2018 Camry XSE V6, 2018 Accord Touring 2.0T and the perennial critical-darling 2018 Mazda6 Signature. The latter was thoroughly overhauled and, perhaps as such, bucked the segment trend by actually selling more in June this year. Each was a range-topping trim level with all the bells and whistles, plus the most powerful engine available. Really, you couldn't find cars closer in power, price and feature content. View 57 Photos Performance and fuel economy Toyota bucked the turbocharged trend by sticking with naturally aspirated engines for the 2018 Camry, and when it comes to its 3.5-liter V6, it's sure hard to argue with that decision. For starters, it produces 301 horsepower. Let that sink in for a moment. A 301-hp Toyota Camry. That crushes the others, while its 267 pound-feet of torque is only 6 less than the Accord. This is a strong, smooth engine that only gets better when you realize it matches the 26-mpg combined fuel economy of the others. Honda, meanwhile, followed the masses by switching to a turbocharged four-cylinder for the Accord's engine upgrade (and its base engine, for that matter). Though its 252 hp is considerably down on the Camry and its 271 lb-ft is only a smidgen more, the Accord's torque arrives earlier in the rev range without feeling overtly turbocharged. It also has 143 fewer pounds to contend with. When wrung out, this new 2.0-liter belts out a beautiful, typically Honda song made possible by the smart 10-speed automatic (the base 1.5-liter is paired to a CVT that results in more drone than mechanical music) that thankfully doesn't draw much attention to itself.
