The Jeep Grand Cherokee Trackhawk is the all-wheel-drive Hellcat you've been waiting for

If the Jeep Grand Cherokee SRT was the venerable SUV cranked to 10, the new Trackhawk goes to 11. Actually, make that 707, because the Grand Cherokee Trackhawk is a Hellcat by another name. Under the hood is the same 707-horsepower supercharged V8 from the sinister corporate cousins Charger and Challenger. The torque rating drops just a bit to 645 pound feet, versus the 650 of the Hellcats, but we don't think many people will be too upset. Especially since Jeep claims the Trackhawk is capable of a 3.5-second 0-60 mph run and a quarter-mile time of 11.6 seconds. The former is right in line with the Challenger Hellcat. View 24 Photos The Grand Cherokee Trackhawk also offers a unique difference to the Hellcats, and its not the SUV body style. The Trackhawk is all-wheel-drive. Power goes from the supercharged V8 to an 8-speed automatic and a single-speed transfer case. There's also an electronic limited slip differential at the back. Jeep beefed up the transfer case with a wider chain that features forged sprockets. The rear drive shaft and half shafts have been strengthened to handle the extra power. Power is split 40/60 front and rear in the default automatic setting, and becomes more rear biased in more aggressive driving modes. In the sportiest "Track" mode, power is split 30/70. In the least aggressive "Snow" mode, power is split 50/50. The sportier drive modes also firm up suspension and decreases shift times. This content is hosted by a third party.

The suspension lowers the SUV a full inch compared with normal Grand Cherokees. Wheels are 20 inches in diameter and 10 inches wide wrapped in 295-millimeter wide tires, either all-seasons or optional three-seasons. An optional forged set of wheels is available, too, which Jeep says will save 12 pounds of weight. The wheels are stopped by Brembo six-piston calipers and 15.75-inch rotors up front, and four-piston calipers and 13.73-inch rotors out back. Jeep says the front brakes are the largest ever fitted to one of its vehicles. Visually, you'll be hard-pressed to tell a Grand Cherokee Trackhawk from the current SRT variant. The bumpers and fender flares are roughly the same. But a tell-tale sign is the lack of fog lights.

Driving the Jeep J6, Shakedown Challenger and other Mopar concepts

Mopar has been a one-stop-shop for factory-backed performance modifications and accessories on FCA products for a long time now. You want a 707-horsepower engine for your old Plymouth Belvedere? Mopar has you covered with the Hellcrate. Maybe you want a lift and off-roading lights on that newly-bought Wrangler? Mopar can accommodate those wants (or needs, we don’t judge) as well. We get to see some of the companyÂ’s weirdest creations every now and then, but rarely do we get the opportunity to drive the FCA Mopar concepts. ThatÂ’s what made this past Woodward Dream Cruise so special: We got to rip some of MoparÂ’s finest and most recent creations up and down Woodward Avenue. Everything from a 1971 Challenger restomod to the brand-new Easter Jeep Safari J6 concept was in attendance, so letÂ’s get right to it. Mopar Woodward View 6 Photos 1967 Plymouth Hellvedere This car is near the pinnacle of what you can do with off-the-shelf Mopar purchases. It was only a humble 1967 Plymouth Belvedere before Mopar dropped the 707-horsepower supercharged V8 from the Hellcat into the engine bay. Sound ridiculous? Yeah, it is. Other parts of it are new as well, including the disc brakes. Good call. However, Mopar didnÂ’t remove the classic car charm from the entire driving experience. The steering, for example, is surely as slow and inaccurate as it was back in 1967. That doesnÂ’t help matters when youÂ’re trying to put 707 horsepower to the pavement with less-than-ideal rear rubber. Floor it in damn near any gear of the Tremec six-speed, and the front end rises straight up as the rear kicks sideways with the force of many mules. There are no electronics such as traction control or stability control to step in and wrangle the car into submission. But hey, who wants them, anyway? The question remains: Should you buy a Hellcrate engine for your classic? If money were no object, the easy answer is yes. Have at it so long as you love smoky burnouts and excessive amounts of horsepower. Just make sure you know how to deal with that much power before you stick your right foot in it.   Dodge Challenger Shakedown View 15 Photos 2016 Dodge Shakedown Challenger Concept WeÂ’re going downhill in horsepower with this restomod, but the drivability and ease of driving goes way up. Dodge showed this “Shakedown” concept at SEMA awhile back, and as with most concept cars, getting a chance behind the wheel is a special opportunity.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
