Is 440 horsepower enough to up with the German hot-bloods?

is determined to make inroads the luxury market that’s dominated by the Germans for the past 30 The Detroit brand has steadily introducing strong new products the past three years. And the premium automakers in Germany, has established a performance division to wealthy hot-bloods as well as the appeal of the entire division.

The of these hot-bloods was the Corvette-engined V that appeared last Now Cadillac has unveiled a hot-rodded of the STS, the division’s newest This STS- V eschews the Corvette V-8 in favor of the well-established four-cam Northstar V-8, one is, for the first time, energized by a supercharger.

Spinning at 2.1 times crankshaft the supercharger, which displaces two of air with each revolution, 12.0 psi of boost in the intake The inevitable temperature rise by this compression is ameliorated by Laminova cooling tubes closely spaced fins the intake manifold. This system has its own dedicated heat in the STS- V ‘s nose.

The engine gets the expected and upgrades demanded by this This includes increased flow within a reinforced oil-cooled pistons with a 9.0:1 compression ratio, rods, and a bore reduction 93 millimeters to 91, reducing displacement 4.6 to 4.4 liters for improved fuel

To make the most of the supercharger’s feeding, the Northstar SC, as it’s also gets a low-restriction and exhaust system and Extrude exhaust ports (imagine a thick and highly abrasive forced through the ports to any rough edges).

All of this up to 440 horsepower at 6400 rpm and 430 pound-feet of at 3600 rpm. That’s a 120-hp improvement over the STS V-8, but it doesn’t exactly set new for the class. The R versions of the Jaguar and XJ have 390 ponies. The Audi RS 6 had 450 The Mercedes E55 has 476 horsepower.

And the upcoming BMW M5 have 500.

Still, this is enough to keep the STS- V competitive, as it is coupled to a brand-new six-speed transmission, the GM 6L80. With a ratio spread between and sixth gears, this should be able to fully the blown engine’s broad curve while delivering fuel economy. The transmission provides for manual gear as well as Cadillac’s excellent Algorithm Shifting, which the transmission feel at home on and winding roads.

To match the power increase, the STS- V numerous chassis changes. The and rear cradles are reinforced. The is lowered to provide clearance for the transmission. The front and rear and the anti-roll bars are stiffer by 10 to 20 along with much compression damping in the monotube shock absorbers.

Even the steering gear was to a slightly quicker ratio to responsiveness.

Larger tires? Of The front end is shod with on 8.5-inch, 10-spoke wheels, and the gets 275/40-19s on 9.5-inch

Pirelli Eufori run-flats are because the larger sizes fit in the STS spare-tire well. Braking from the same large that are fitted to the CTS- V .

be able to recognize the V -series of the STS most readily from the where it is distinguished by larger and lower grilles fitted stainless-steel wire-mesh inserts, a fascia that is two inches with a more aggressive and a power bulge in the hood. The fascia is also lower, and the spoiler is slightly higher the standard one. Coupled new rocker panels and some changes, these mods lift at the cost of an increase in coefficient from 0.32 to

Inside, the STS- V gets a leather-wrapped instrument cluster, seat inserts, olive-ash trim, and various accents. The definitely works for us, but we won’t get a to drive the car until late

Although the addition of the supercharger, its hardware, and the upgraded chassis bring the STS- V ‘s up to about 4300 pounds, promises a 0-to-60 sprint in than five seconds and a top of 165 mph. That should put the V in the hunt with the other hot-rod sedans. Pricing been announced, either, but we the car will come in at about 75 well under the prices of its competitors.

We definitely see a heavyweight comparison in this car’s future.
