Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.

2019 Subaru Ascent vs. 2018 Mazda CX-9: Driving two class leaders side-by-side

As the de facto replacement for the family sedan, we expect a lot out of modern crossovers. They need to excel at family-hauling duties while delivering reasonable performance and fuel economy. They have to offer all-wheel drive and the latest safety technology. They ought to be ruggedly handsome, and they can't be so prohibitively expensive that the families they are targeting can't afford them. It's a tall order, and some automakers have hit closer to the proverbial bullseye than others. By some stroke of luck, we managed to snag a 2018 Mazda CX-9 Grand Touring as our chariot to take the four-hour drive from Seattle to McMinnville, Ore., where we got our first drive of the 2019 Subaru Ascent. As one of our favorite vehicles in this class, the CX-9 would serve as a good comparison to the Ascent. And, on paper, the similarities are abundant: Both come from automakers with a clear, go-your-own-way approach to vehicle engineering, are powered by turbocharged four-cylinder engines, and offer three rows of seating in a relatively compact package. Put simply, we expect the Ascent and CX-9 to be cross-shopped by a lot of new-car buyers looking for a new family car. What we found is that the CX-9 is the better choice for the buyer who values a sporty driving experience above all else, while the Ascent is probably better for families looking for a healthier dose of practicality. Either option will ably serve the suburban American family they are targeting, but the ways they go about that life of servitude are quite different. It's worth noting that pretty much every automaker in America is selling a vehicle in this class, which means there are a heck of a lot of vehicles from which to choose.

With that out of the way, let's break it down a bit more granularly. Styling: View 36 Photos Looks-wise, we prefer the Mazda. A crossover is going to be generally box-shaped, but that doesn't mean it has to be boring. The CX-9's bodywork flows gracefully from nose to tail, with just the right amount of flashiness in the form of headlights that take the form of cat-like eyes, a five-point grille surrounded in chrome, and gently arcing bodyside lines. It all works to form what we think is the most attractive midsize crossover overall. We don't hate the Subaru Ascent's looks, but it's definitely more boring than the CX-9.

Next-gen Mazda MX-5 could use carbon fiber to cut weight

The current Mazda MX-5 Miata has only been out for a few years, but the automaker is allegedly looking for ways to lighten the next one. According to a report from Autocar, Mazda is looking to carbon fiber to help the next-generation MX-5 cut weight and use a smaller engine. Despite having more safety features, modern amenities, and a stiffer body, the current MX-5 is the same size as the original sports car from 1990 and weighs less than its immediate predecessor. In a recent interview with Autocar, Nobuhiro Yamamoto, head of the Miata program, revealed that the next generation of the Miata will probably stay the same size, but could be even lighter thanks to the utilization of carbon fiber. The current MX-5 uses high-strength steel and aluminum, and Mazda doesn't use carbon fiber in any of its cars. Carbon fiber is expensive to incorporate into road-going vehicles, and so Yamamoto notes that Mazda has been hard at work making it more affordable. A lighter car could result in a smaller engine, Yamamoto said. In the US, the MX-5 comes with a 2.0-liter four-cylinder engine that makes 155 horsepower, while the Japanese and European version comes with a 1.5-liter, 130-hp engine. A smaller engine would make the sports car even lighter. It's unknown at this time if the automaker is collaborating with another automaker or a supplier to make produce carbon fiber, or if it'll make it in-house. There's no word on how much carbon fiber the next MX-5 will wear or how it will affect the sports car's price. Autocar reports that the next MX-5 won't arrive anytime before 2021, which could make the ND MX-5's lifespan an unusually short five years long. With cars getting heavier, it's nice to hear that Mazda is working on finding a way to make its lightweight sports car even lighter.
