The 2006 STS-V boasts a maximum power of 476bhp at 6,400rpm while the XLR-V is rated at 448bhp at 6,400rpm.
"Cadillac's V-Series is founded on the idea of taking the strong performance and luxury attributes of our core vehicles and extending them even higher," said Jim Taylor, Cadillac general manager. "As a result, Cadillac's V-Series, CTS-V and STS-V sedans and XLR-V hard-top convertible roadster – are serious performers that compete with the high-end performance variants of any manufacturer and now provide European customers with new alternatives.”
The 4.4 litre Northstar V-8 supercharged DOHC engine features variable valve timing and represents the most output ever for a production Cadillac.
With sales in Europe scheduled to begin in the first quarter of 2006, pricing for the STS-V and XLR-V will be announced at a later stage.
