So, just how different are the Fiat 124 Spider and Mazda MX-5 Miata?

"We leveraged a great platform." That's how Bob Broderdorf, Jr., Fiat's North American director, summarizes the creation of the 124 Spider. We all know Fiat's new roadster shares its underpinnings with the fourth-generation Mazda MX-5 Miata, but there are a lot of key differences to keep them separate in the eyes of consumers. Mazda may have engineered the platform, but Fiat added many of its own touches. Here, we'll take a closer look at the spec sheets of the two cars, and summarize the major differences between the Japanese and Italian roadsters. If you need a refresher, read our full First Drive of the 2016 MX-5 Miata, and glance at all the Fiat 124 Spider details in this post. Design Fiat Chrysler design lead Ralph Gilles is super excited about this car. "I think it's going to change lives," he told the assembled media at an event in Auburn Hills, MI, earlier this month. Yes, it's definitely exciting to add a small roadster to any lineup, especially one that uses such a proven platform. But we're not sure people are going to get all that jazzed about it from a design standpoint. You'll either love it or hate it, and we're kind of leaning toward the latter. Every single body panel is new, and the design is "100 percent Italian." There are a number of creases and angles throughout the exterior, with a squared-off rear end and rectangular taillamps. Fiat trusts you'll be able to spot the similarities between the new 124 Spider and the original, but we're not so sure. We can see a bit of the old car's grille on the new car's face, and the dual hood blisters are a nice throwback touch, but that's about it. Trust us when we say that this car looks way better in photos. In person, it really didn't wow us. Of course, beauty is in the eye of the beholder. One colleague told us his wife, a long-time Miata owner, hates the look of the new one but will absolutely adore the Fiat. Good for her, and good for Fiat. But based on design alone, we'll take the Mazda every single time. What about you? Dimensions When Broderdorf said Fiat leveraged the Miata's platform, that means the Italians took it as-is. The two cars ride on an identical, 90.9-inch wheelbase. The front and rear tracks lengths are the same, at 58.9 and 59.1 inches, respectively. But that's where the similarities end.

What a 28.5-liter LSR engine sounds like firing up for the first time in 100 years

Racecars seem to keep getting quieter these days, and if electric vehicles and fuel cells ever fully take over motorsports, then the bang, pop and growl of internal combustion engines may be gone for good. This clip of a Fiat S76 land speed record racer awaking after over a century of being dormant shows just what we would miss so much. The four-cylinder engine in this Fiat displaces about 28.5 liters, making it among the largest automotive engines ever, and it gives each cylinder around as much capacity as the whole mill in a Chevrolet Camaro Z/28. Once this thing starts firing with no exhaust in place, the look and sound is like a demon at work with a rain of fire and sparks. This clip is just the trailer for a documentary called the Beast of Turin chronicling the history of this period of racing. The movie also focuses on the rebuild and restoration of the S76 after over 100 years. If the rest of the film lives up to this tease, then it looks like something to watch for.

Fiat recalling 2014 500L over dual-clutch transmission

Much like it did yesterday, Fiat Chrysler Automotive is announcing a voluntary recall of the five-door Fiat 500L. Where yesterday's recall covered Jeep and Dodge SUVs over performance issues with the brakes, today's bulletin is perhaps more serious. Over 19,000 500Ls equipped with the Fiat-sourced, six-speed, dual-clutch automatic are being called in for a software update that should sort out the issues some customers are experiencing with the gearbox. Those troubles mainly consist of 500Ls that won't shift out of park and don't respond or are slow to respond to commands for gear changes. There have been no reported injuries or accidents due to the problems, which investigating engineers believe is caused by a microcontroller component that doesn't react well with temperature extremes. Of the 19,500 vehicles being recalled, around 20 percent are in dealership inventories. The vast majority of the cars (18,100) are in the US, while the remaining 1,400 are up north, in Canada. Fiat will be covering the costs of the software reflash and will begin notifying customers soon. Scroll down for the official release from Fiat Chrysler. Statement: Software Update March 7, 2014 , Auburn Hills, Mich. - Chrysler Group is recalling approximately 19,500 cars to upgrade their transmission software. Chrysler Group engineers launched an investigation after reviewing reports that some vehicles equipped with dual dry clutch automatic transmissions would not shift readily out of park and/or their transmissions did not receive, or were slow to receive, an intended gear selection. Chrysler Group is unaware of any related injuries or accidents. The investigation discovered the function of one microcontroller component may be compromised by certain temperature extremes. A software update resolves the issue. Affected are certain 2014 Fiat 500L models, of which approximately 20 percent are in dealer hands. Repair costs will be borne by the Company. Affected customers – approximately 18,100 in the U.S. and 1,400 in Canada – will be contacted and advised when to schedule service. Of the total, an estimated 200 vehicles may require shift-module replacement to ensure hardware-software compatibility. Customers who remain concerned may call 1-800-853-1403.
