Dodge CEO and Gas Monkey Garage dissect the 10-second Challenger Hellcat

So far, whenever we've seen the 2015 Dodge Challenger SRT with its 707-horsepower, supercharged Hellcat V8, the muscle car has been smoking its tires. Dodge is finally proving that the SRT can do more than ruin perfectly good sets of rubber, though. In it's latest video, company CEO Tim Kuniskis hands the Hellcat off to the guys from Gas Monkey Garage to show how quickly the automaker's most powerful model can make it down the drag strip.
Of course, the only fitting contender to race against Dodge's latest top muscle car is its grandpa - a Hemi-powered 1971 Challenger, in this case. Before getting to the main event, the hosts also show off some of the SRT's unique features like the blanks in the grille that feed the intercoolers. We'll go ahead and spoil that the Hellcat makes its pass in the 10-second range, and the video admits the tires on the production version would take just a touch longer to cover the quarter-mile. However, you have to watch film to see just how quick it actually goes. Scroll down to see a classic example of American muscle drag racing against its modern legacy.

Hennessey Dodge Demon sets hellishly fast quarter-mile time

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk. The folks at Hennessey apparently think that's not nearly extreme enough. So, the Texas-based tuning outfit has turned the Demon into a 1,035-horsepower mega beast that runs a quarter-mile in 9.14 seconds at 152 mph. That's fast, really fast. In fact, the HPE1000 is now the world's fastest Dodge Demon, having set its record-setting pace at Lonestar Motorsports Park on May 8. "The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car's impressive track times to an industry leading level." said president and company founder, John Hennessey. For comparison, the stock Dodge Demon is credited with running the quarter-mile in 9.65 seconds at 140 mph. The main HPE1000 modification involves replacing the stock 2.7-liter supercharger with one that's a staggering 4.5-liters in capacity. Also included in the Hennessey toy-chest are stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, along with custom engine management calibration. When all is said and done, the HPE1000 Dodge Demon delivers a total of 1,035 horsepower at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm. While the standard Demon accelerates from 0-60 mph in only 2.3 seconds, the Hennessey variant trims this down to only 1.9 seconds. That's quick enough to make a Bugatti Chiron blush. Hennessey hasn't stated what all this will cost, though the company did say production of these devilishly fast Demons will be limited to only 50 examples. Customers also receive a 1-year/12,000-mile warranty, which seems a nice touch for a car that's downright scary with its performance specs.

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.
