FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Fiat brings back throwback 1957 Edition for the 500

Fiat is bringing back its retro-styled 1957 Edition treatment for its 500 cabrio and hatchback models, an homage to the original 500, which debuted in 1957 as the Nuova Cinquecento. It's like a Vespa-ization of the little Italian subcompact. For an extra $995 and based on the Lounge trim, the 1957 Edition brings a new, retro fascia with throwback Fiat badging, white exterior mirrors and a choice of white, green or blue 16-inch retro-inspired wheels. You get a two-toned paint job with a white roof on hatchback versions and a black soft top on cabrio models, plus choice of three retro-inspired paint colors: celeste blue, chiaro (light green) and bianco ice (white). Inside, designers have contrasted a mostly ivory interior with marrone brown leather seats decorated with ivory accent stitching on the setbacks, perimeter and cushions. There are also ivory door-trim panels and a marrone brown leather shift boot with manual-transmission models. The steering wheel is wrapped in leather and continues the ivory-brown theme. It's accented with a retro Fiat badge. The Fiat 500 comes standard with the new 1.4-liter MultiAir Turbo engine, which boost output to 135 horsepower and 150 pound-feet of torque and features a sport-tuned exhaust. It's paired with a standard five-speed manual transmission or an optional six-speed automatic. The 1957 Edition was last available for the 2016 model year in a slightly different guise and price point. You can once again retro-pimp your 500 at dealerships starting this fall.

We need the sound of the Abarth 124 Spider in our lives

We've come to expect a certain sound to come from an Italian roadster, whether it's a Maserati, Ferrari, Lamborghini, or Pagani. But where those all boast eight, 10, or even 12 cylinders – naturally aspirated or otherwise – the comparatively humble little Fiat 124 Spider packs a turbo four. And that type of engine seldom offers the kind of sonorous exhaust note that the big boys can make. Fortunately the chianti-swilling grease monkeys at Officine Abarth are on the case. Fiat's performance brand revealed its take on the new Mazda-based roadster at the Geneva Motor Show a month ago, incorporating all manner of enhancements over the standard model. That includes a modest 10-horsepower boost over stock and a Record Monza exhaust. And as you can hear from this video, captured at a Ferrari event somewhere in Europe, it gives the new Scorpion roadster a real audible sting in its tail. Unfortunately the version we get Stateside – revealed as the Fiat 124 Spider Elaborazione Abarth at the New York Auto Show – lacks some its European counterpart's enhancements, including those extra 10 cavalli. The car in this video is Euro-spec, and Road & Track reports the US model will be "more refined" though still capture the Abarth spirit. Related Video:
