Spy Shots: Cadillac CTS-V Plus
Even more horses for the CTS? Bet on it.
by Brenda Priddy (2004-05-10)

As if the 400-horsepower CTS-V Series isn't enough, we photographed General Motors' Performance Division engineers testing an even higher performance version.

Referred to as the CTS-V Series Plus by spectators at the Nürburgring, this CTS mule is said to be powered by a 6.0-liter V-8, and sources are estimating the horsepower to be in the 475-500 range. General Motors is aggressively testing this more powerful CTS, but production plans have not yet been confirmed.

The vehicle show here is actually an older CTS-V mule. The higher-performance CTS-V Plus uses a larger-displacement pushrod small-block engine, so the hood hump should disappear in production

Look for a supercharged 4.2L Northstar in the STS-V.

The new Northstar displaces 4.6L, and yes according to Mark LaNeve, it will be Supercharged, but there are now rumors thanks to this thread of a 700HP Vette powered STS...that would be very very exciting and would blow the M5 way out of the water. Here is the link to the original information: [/b][/quote]
Actually, I checked with my sources again and they came up with an LC3, 4.4L supercharged Northstar, to be used in the V-series STS, XLR, and SRX. It must be a variant of the Bonneville's Northstar.

But who knows, maybe my sources are wrong.

Too add to R.E Sanchez post, I found this link on another GM Forum site about the CTS-V Plus & STS-V

Here is a small excerpt from

"These shots show muscled-up Plus versions of the mid-size CTS-V and full-size STS-V saloons testing on the Nurburgring. The current CTS-V, on sale in America, already delivers 400bhp from its V8, but GM has engineered the Plus's V8 to put out nearly 500bhp. Reports suggest the STS-V Plus could develop as much as 700bhp from its tuned version of the Corvette's 6.0-litre V8. 0-60mph shouldn't take much longer than five seconds, for either car."
Umm.. Isn't five seconds alittle conservative as a 0-60 estimate for vehicles packing 500 and 700 horsepower respectively?
Not if it's a medium duty truck.

But for a car, yes, it seems way conservative.
