MotorWeek revisits the awesome, original Dodge Viper

MotorWeek is bringing the automotive world a wonderful blast from the past with its latest Retro Review. Not only does the video feature the now-famous, original Dodge Viper, but this is also a chance to watch one lapping Pocono International Raceway in a test of track prowess. This segment was MotorWeek's first chance to unleash the Viper around a racecourse, and the show took advantage of the opportunity. In addition to the usual 0-60 mph and quarter-mile tests, the 400-horsepower V10 is let loose to do lap after lap. The clip offers a great dose of nostalgia and is worth a watch to remember the intense enthusiasm surrounding the Viper at the time.

Here are the Challenger SRT Demon's bare-minimum performance numbers

This week's Dodge Challenger SRT Demon teaser video provides what seems like more concrete evidence than any of the others before it. We say it seems that way because the numbers flashed on the screen are likely not showing us everything the car has to offer. So we're looking at these as the minimum performance stats and expecting Dodge to reveal even crazier numbers alongside the car next month. The video also provides some hints at features and modes the car will offer. Let's pick it apart. First off, there's the performance data from the various SRT Performance Pages screens. The 0–60 mph time is 3.0 seconds, which compares well to the "regular" Hellcat's 3.5-second manufacturer claim. Then there are two 0–100 times: 6.08 and 6.8. An eighth-mile time of 6.6 seconds at 125 mph and a quarter-mile time of 0.5 seconds at 129 mph lead us to believe the driver lifted off the throttle in that second eighth-mile and that the car will actually do the quarter in the low 10s. For reference, Dodge claims an 11.2-second quarter for the Hellcat on its street tires and a 10.8 with race slicks.

A graph shows it heading up toward 10 psi but the final spike is obscured by a Demon head. Cute. There's a hint at horsepower and torque numbers in a graph on the Dyno page, which shows both peaking around 750. In every shot of this video, the clock is set to 7:57, which we think means it either has that much power or, well, more. We think there's more to it because it appears that part of the graph above the dyno run shown, which would reach to 800 or 850, has been blanked out. A horsepower total of 808 would be a nice complement to the Hellcat's 707, don't you think? We can see from the shift indicator screen that the car will come with or at least offer the eight-speed automatic that's also available in the Hellcat and other Challengers. That's likely to be the best option for drag racing. The Demon's user-defined shift light feature, which lets you choose an optimal shift rpm for each individual gear, also suggests that a six-speed manual will be available. We'll cover the many modes and settings highlighted in this video in a separate post. There's a lot to discuss. Related Video: This content is hosted by a third party.

Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.
