Less than a year after its introduction, the first special-edition SRT Viper has arrived, the SRT Viper TA, and in keeping with the car's racing success, this new variant is a capable track-day special. TA stands for 'time attack', referring to the qualifying-style competitions popular among American racing sanctions.
Fundamentally, the configuration of this American supercar is unchanged from its outrageous original spec. The massive 8.4-litre V10 makes the identical 640bhp and 600lb ft as the standard SRT Viper, and still delivers neck-straining acceleration. The ratios for the short-throw six-speed manual gearbox and final drive are unchanged.
Yet the devil is in the details, as they say, and mostly under the skin. The suspension is thoroughly improved for track work, with spring rates up 20 percent. Stabiliser bars are over 30 percent stiffer and the two-mode, electronically adjustable Bilstein DampTronic dampers, which are revised to suit the changes in stiffness, are restricted to just Sport and Race settings. There is no Street setting.
SRT fits the lightest available original-equipment forged alloy wheels, finished exclusively in matt black, and wraps them in wide Pirelli P Zero Corsa tyres. The aggressive alignment settings are specific to the TA and are more suited to chasing lap times than enjoying long-distance drives through California.
