Viper news!!!!
 

The Chrysler Group's flagship brash and unrestrained V-10-powered sports car is significantly more venomous for '08. The underlying look inside and out is familiar, but the big changes are underhood, where the V-10 engine has been pushed out to a super-sized 8.4-liters, for 600 hp and 560 lb-ft of torque and a 0-60 time of well under four seconds.

With help from racing specialists McLaren and Ricardo, engineers looked to raise the V-10's engine speed and improve its breathing. In doing so, the engine has improvements to the cooling system, plus new iron cylinder liners, cross-bolted main bearing caps, and powder-metal forged connecting rods. New CNC-shaped cylinder heads with larger valves and variable valve timing cap the new engine, improving response and efficiency, and a new two-piece intake manifold brings better airflow.

To match the engine improvements, the Viper gets a new clutch that's actually smaller in diameter, but its twin-disc design handles the torque with reduced pedal effort - a common complaint on the current model - while reducing rotating inertia. This is mated to a new Tremec six-speed manual with a wider range of ratios, improved synchros, and reduced shift-knob travel. In addition, the Dana rear axle gets a new speed-sensing, limited-slip differential for better traction.

Thanks to Brembo dual opposing-piston calipers front and back, the Viper can now brake from 60 mph to a stop in less than 100 feet, and go from a zero to 100 to zero in just over than twelve seconds.

Changes to the Viper's outward appearance are minor overall, but in front the '08's differences are most pronounced, with a hood that's been redesigned with a larger scoop for better induction and aggressive-looking louvers for improved cooling.

Previously, Vipers came in little more than basic-black inside, with a kit-car feel brought on by parts-bin components and non-matching surfaces. The current Viper was a big step up in civility, but for the '08 Viper makes another step ahead with more than a few interior choices. It will be available in five different interior colors with a choice of bezel finishes, along with other customization options.

Assembly will remain at the Chrysler Group's Conner Avenue assembly plant in Detroit , with first deliveries of the '08 planned for spring.

Goodbye zo6

RE: Viper news!!!!
 

Thank Godfor new interior, hopefully it will offer navigation.I don't think the z06 will be left out for long, they may not be able to shave off more weight, but they could beef the engine up again.

*And if anyone isn’t impressed, these engine "Dynamic" power increasecomparisons are like going from 5.7 Hemi to 6.1 Hemi without as much displacement change and having even slightly more power.****Corvette had to completely stroke and bore the engine 1 whole liter, as well as upgrade cam and heads to make that much more total power difference.


Simply putt, this may be the single most efficient engine power upgrade of a factory car in the history of the fu*kin planet.

Not bad Dodge,

Actaully the interior is not that different, just different colors.

The next "faster" vette is suppose to he supercharged. I find it interesting when DC beefed up the V10 they went back to forged internals, first time since the 90s for the V10. My guess is they did this in anticipation of having to SC as well down the line.

RE: Viper news!!!!
 

Did you notice they are using the 6.1 Hemi internals, Its just pistons really, I think the Viper might just get the 700 all motor set up this engine has already been tested for. (If they need it) I really like this car now though.
