2015 Jeep Renegade Sport 4x4 Quick Spin [w/video]

Which is the most entertaining Jeep Renegade you can get? While one might make an argument for the Trailhawk model and its accompanying off-road hardware and consequential go-anywhere ability, that car comes with one glaring flaw – its 2.4-liter engine and nine-speed automatic transmission just aren't very entertaining. Instead, I submit the turbocharged, 1.4-liter base engine and its accompanying six-speed manual, a position that was reinforced after a recent stint behind the wheel of a very basic Sport 4x4. Not only do you get a fair amount of the Trailhawk's off-road ability – the Selec-Terrain system and a 4WD Lock mode are standard, but you'll be without the 20:1 crawl ratio and Rock off-road mode – you'll also enjoy a more dynamically interesting powertrain. Read on to see why the force-induced Renegade might just be the way to go. Driving Notes My first date with the Renegade was on the mostly empty, winding roads of northern California. There, the 1.4-liter turbocharged inline-four with 160 horsepower and 184 pound-feet of torque felt fine – with no traffic and few stoplights along the drive route, it was easy to keep the engine on boil. But this engine isn't as enjoyable in day-to-day suburban traffic. Power arrives suddenly – peak torque comes between 2,500 and 4,000 rpm – and if you don't use it, you lose it. There's not much oomph in the higher end of the rev range. With such a peaky powerband, it's easy to get caught flat-footed if you're not paying attention. Thankfully the manual transmission makes it simple to stay engaged and in the correct gear. The stick-shift is enjoyable to use, with a firm clutch that's easy to modulate and shift action that isn't sloppy or vague. The 1.4-liter engine sounds good. Turn down the stereo, stomp on the throttle, and you'll be treated to a delicious turbo whistle and a smooth exhaust note. I've said it before and I'll say it again: I want Mopar to offer the Fiat 500 Abarth's exhaust on the Renegade. It'd be fun. If you do prefer the stereo, know that the Renegade's standard four-speaker unit is weak. Base models don't offer Bluetooth or satellite radio, but you can add both of those luxuries, two extra speakers, and a five-inch touchscreen for just $695. Not a bad bargain. The Koni frequency selective dampers do an excellent job of managing both small, frequent imperfections (like freeway expansion joints), and the bigger potholes that still haven't been fixed after the havoc of Detroit's winter.

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

The List: Best of proving grounds

Proving grounds are where automakers and enthusiasts alike go to push their vehicles to their mechanical limits. The Rubicon Trail, located in the Sierra Nevada, is the ultimate off-road test, while Germany's Nurburgring is a grueling 13 mile road and track course. Jessi and Patrick visit both iconic proving grounds in this "best of" compilation of The List.
