2020 Fiat 124 Spider Abarth Review | Miata Arrabbiata

The Mazda MX-5 Miata is one of our favorite sports cars, and it’s hard to imagine how it could be improved – especially after Mazda added a revvier, more powerful engine for 2019. That presents a potential issue for its platform mate, the 2020 Fiat 124 Spider, which hasnÂ’t received a similar update. So we spent some time behind the wheel of an Abarth version on the road and on a track to see if thereÂ’s a reason to choose it over its new-and-improved twin. While itÂ’s unchanged for 2020, the 124 AbarthÂ’s engine does the lionÂ’s share of the work charming the driver. The 164-horsepower 1.4-liter turbocharged inline-four is no longer more powerful than the MiataÂ’s 181-hp 2.0-liter naturally aspirated engine, but the Abarth remains the torque king, packing 184 pound-feet to the MiataÂ’s 151 lb-ft. More importantly, the Abarth makes its power down low, feeling punchier at low rpm and taking far less work with the shifter to keep it in the power band. ThatÂ’s particularly nice around town when you might not want to push the car to redline repeatedly. The trade-off is that it feels much less exciting near redline, and the throttle response is lethargic compared with the snappy Mazda engine. And on a racetrack, that extra precision and power at the top end makes for a more rewarding experience. Besides user-friendly torque, what sets the 124 Spider Abarth from the Mazda is the sound. The Abarth is the only 124 available with the special Record Monza exhaust, and it makes the Fiat growl and snarl like only Italian cars can. And of course, itÂ’s all the better when you drop the top, expediting the sound to your ears. It makes the car feel more expensive and unusual than it is. Now, the Miata has its own more refined purr thatÂ’s lovely, too, but the FiatÂ’s soundtrack is giggle-inducing at every drop of the throttle. Capping off the powertrain is the FiatÂ’s transmission that I found to be just a bit better than the ND MiataÂ’s. It has heavier, more mechanical shifts that arenÂ’t as notchy as the MiataÂ’s. ThatÂ’s still a compliment to Mazda, though, as the FiatÂ’s transmission comes from the previous-generation NC Miata. It was chosen to handle the turbo engine's torque. The only complaint is the bizarrely shaped shift knob that never felt comfortable regardless of my grip. The AbarthÂ’s styling is another point of differentiation.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.

Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:
