With the supercharged 6.2 Hemi delivering 707 horsepower to the Dodge Charger and Challenger, the Viper boys are reportedly looking for ways to get back on top. While the Viper may be superior on a tight racing course, the straight-line performance of Charger and Challenger, in five-seaters with all the amenities, large trunks, and automatic or manual transmissions, is a challenge for Team Viper — as is the current series of Corvettes.
The power difference is not that large, and Viper no doubt has a major edge in low-end torque, but some people just look at the top number and say, “707 is bigger than 640 (and for torque, 650 is bigger than 600.)”
We have now had two reports of supercharged V10 engines being delivered. Either way, the supercharger would presumably allow Viper to pass 707, and quite possibly, if the block, internal parts, transmission, and body can endure it, shoot up to, say, 800. That could restart lagging Viper sales and decisively put Viper back on top of the Corvette in performance comparisons, albeit at a high development and production cost.
Why not shoot for, say, a stunning 1,000 horsepower, one may ask? Because that would require a new and expensive transmission and differential, more substantial cooling upgrades, much more incoming air, and quite possibly a new body to deal with the added stresses. Cars are systems, and upgrading the engine often requires upgrades to a large number of other components. The engineering and production costs would skyrocket. The Tremec TR-6060 in the Viper can handle, at most, 650 lb-ft of torque — no coincidence that the Hellcat maxes out at that number (which is also roughly the capacity of the ZF eight-speed). Even the Tremec TR-9008 can only handle 664 lb-ft. Tremec does have a “Magnum XL” which is good for 700 lb-ft, but would require changes to work in the Viper.
Note: we have now had one other source say that supercharged V10 engines have been delivered to Chrysler.
Dodge has released pricing for the full Charger lineup, starting with the V6/eight-speed Dodge Charger SE at $28,990 (all prices include $995 destination for the “49 states”). Charger was thoroughly renovated for the 2015 model year, with a new look, suspension and electronics revisions, a standard eight-speed automatic for ever engine, and other upgrades. The top Charger, the SRT Hellcat, has [...]
Months after unconfirmed reports made it to Allpar’s pages, the power of Automotive News, in the person of reporter Larry Vellequette, pried a key fact from Chrysler executives — that they cast and build “Ferrari” engines for Maserati. As our sister site pentastars.com reported, the engines are actually cast in Kokomo, and machined in the Trenton Engine plant, using a mixture of [...]
Allpar’s informal sources have agreed that there are plans for a new Dodge Viper ACR, debuting for the 2016 model year, possibly replacing the current TA (Time Attack) model. Artist suzq044 provided the following rendering, which uses SRT’s trademark black wheels and a Dodge concept-car semi-rendering. The Viper ACR may have a mild power boost, but will be mainly a suspension and/or airflow upgrade, to increase track [...]
The 2017 Jeep Wrangler may leave its historic steel body-on-frame construction and Toledo plant behind, according to Chrysler CEO Sergio Marchionne, as quoted by Automotive News’ Larry Vellequette. The current Wrangler has good mileage for rugged four wheel drive vehicles, but poor economy overall, at around 17/21 mpg (depending on model and transmission). Mr. Marchionne said the Wrangler will need to lose weight [...]
Keeping a years-long tradition, Chrysler today released a number of “teaser images” for concepts to be revealed at the SEMA aftermarket show in Las Vegas, Nevada. Each brand is covered, though Chrysler has but one car — the 200S. That can be explained by the status of the brand’s three cars: the 2015 300 has yet to be launched, and the [...]
