Fiat diesels might also cheat emissions tests

Et tu, Fiat? Fiat is the latest automaker to come under suspicion for excessive emissions from its diesel vehicles. So far the trouble is only in Germany, as opposed to VW's trouble in multiple countries. And instead of using VW's method of installing software that identifies when the car is undergoing an emissions test and only then turning on emissions control devices, Fiat is running out the clock. Because the German emissions test lasts around 20 minutes, Fiat is accused of having its NOx emissions control systems operate only for the first 22 minutes when the car starts up. This potential new bombshell was first reported by Bild am Sonntag, a German newspaper. Bild says that the Italian automaker is under investigation by German authorities after a test of a 500X revealed this time-based method. Bild also says that Bosch tipped off the German authorities about Fiat's strategy. German transport minister Alexander Dobrindt released a report of new tests of 53 diesel cars and highlighted Fiat's numbers, saying, "We will need to carry out further tests on Fiat models." In February, the environmental lobby group DUH found that a 500X that had been running for a while emitted more NOx than one with a cold engine. Fiat said at the time that it had conducted an internal review and found that its diesel engines comply with the law. Of course, thanks to VW's diesel scandal implosion last fall, questions have been emerging from regulators around the world about diesel emissions from passenger vehicles. Mitsubishi was recently suspected of diesel emission irregularities in Japan. A recent lawsuit in the US accuses Mercedes-Benz of using a cheat device. Greenpeace has raised questions about the testing method that German authorities are using to test diesel vehicles. And on and on and on.

The Fiat 500X packs 2.4 liters of disappointment

Our long-term 2016 Fiat 500X is a fine little crossover that's nearly undone by a underwhelming and often frustrating powertrain. The 2.4-liter naturally aspirated four-cylinder/nine-speed automatic combo can be found in a number of FCA products. In every single application I've used this engine, the takeaway has been the same: It's a boat anchor. I like our 500X, I really do. I haven't spent as much time behind the wheel as I would like, but I've put thousands of miles on its platform twin, the Jeep Renegade, and two vehicles are essentially the same underneath. The Tigershark 2.4-liter makes 180 horsepower and 175 lb-ft of torque, good numbers on paper, but in practice the engine is buzzy and slow to rev. The engine feels dated. In contrast, the base 1.4-liter turbocharged engine feels much more lively despite being down 20 horsepower. The low-end grunt is owed to the 9 additional pound-feet of torque the engine makes over the 2.4-liter. It may not match it on the top end, but not many people are running a 500X to redline. The issue I have is that the 2.4-liter is the only available option on the higher-spec models like our Trekking Plus, so if you want some options you're stuck with this engine. The 2.4-liter is exclusively paired to a 9-speed automatic transmission that's built by ZF. As great as some of ZF's other gearboxes are, this 9-speed is varying degrees of bad in every application that I've used it, including the Honda Pilot, Acura TLX, and Jeep Cherokee and Renegade. Shifts can be abrupt, and the manic transmission is constantly hunting in an effort to find the most fuel-efficient gear. More than once I've been left waiting for a kick down in order to move with some gusto. Don't let my harping about the powertrain warp your vision of the 500X. It's a fun little vehicle and arguably Fiat's best product (the 124 Spider is mostly Mazda), but it's frustrating when a pleasant little crossover is brought down by such a lackluster powertrain, made worse by knowing the 1.4-liter is so much better. There's an easy fix, Fiat: Offer the 1.4-liter in all engine trims. And to be fair, it's almost kind of fun around a racetrack. See the video below. Related Video:

In the Fiat 500X, the little things leave big impressions

When it comes to evaluating cars, we at Autoblog strive to tell you about the important things like how well they handle, how fast they are, and how comfortably they ride. These are all key pieces in the good car puzzle. The thing is, some cars also have small, but endearing details that are glossed over because they won't make or break our opinions of the vehicles. But they're features that make us smile anyway, and our long-term 2016 Fiat 500X happens to have a couple of them. The other week I had the Italian crossover for a day, and when I took off for lunch, I found the first surprise between the front seats. Unlike some other automatic transmissions with manual shift gates, this one actually uses the proper, racing-style sequential layout: pull back to shift up, and push forward to shift down. Some car companies flip that pattern, which I can only assume makes more sense to people that don't think about shifting. The 500X's other little surprise came that night as I drove home, but to properly explain why I loved it, I have to first talk about a different car. I own a 1999 Mazda MX-5 Miata, and one of my favorite things about it is that I can cruise around with one hand on the steering wheel and my elbow resting on the window sill. It's the most chill driving position imaginable. Unfortunately, as beltlines have crept higher and higher, and doors have migrated farther from the edges of the seats, the opportunity to drive this way has effectively vanished. To my delight as I drove home in the 500X, I discovered the little crossover bucked the trend. I'm not sure how, but it has window sills that are prime elbow perches. Neither of these features change my overall opinion of the vehicle, but they're worth noting because Fiat didn't have to include either of them. It's just a mass-market crossover, so a racing-style shifter and a comfy window sill would probably go unnoticed by most buyers. Yet, despite those facts, some designers decided the car would be better with these details. For that reason, I'm happy to draw attention to these designers' extra effort, and I will appreciate it every time I'm behind the wheel of our 500X. Related Video:
