Raw figures rarely relate the whole story. But in the case of the fourth-generation Audi S4, they do provide a reliable guide as to the overall effectiveness of its new 3.0-liter V6.

Running a Roots-style supercharger that sits between the cylinder banks and operates at a maximum 24.7 psi, the V6 cranks out 333 hp at 5,500 rpm. This is down 11 hp from the third-generation S4's naturally aspirated 4.2-liter V8.

But the blown V6 also delivers 22 lb-ft more torque than the V8, an impressive 324 lb-ft being released between 2,900 rpm and 5,300 rpm. So there is no great hardship in the loss of two cylinders and 1.2 liters of displacement.

It is sufficient, Audi claims, for an official 0-to-62-mph time of just 5.1 seconds-- 0.8 second less than the old S4 and just 0.2 second shy of the time Audi quoted for the last RS4. A more-telling indicator of real-world performance, however, is the 50-to-75-mph fourth-gear time of just 4.4 seconds.

That is quick by any standard and reflects the effectiveness of the V6's prodigious torque in shifting the S4's 3,637-pound curb weight. Top speed is still limited to 155 mph, but there is little doubt the new Audi would haul beyond this if left to run all the way to its 7,000-rpm cutoff in top gear.

What is even more impressive is that the S4's supercharged V6 achieves all this with 27 percent better fuel economy than the V8. Audi puts the combined fuel-economy rating for the new S4 at 24.9 mpg.

As S4 tradition dictates, power is channeled to all four wheels via a standard six-speed manual gearbox. You can also choose a rapid-fire, seven-speed twin-clutch unit. But beware: Despite offering a manual mode and remote shift paddles, it always acts like an automatic.

Rather than holding on to gears as a proper manual does, the slick-shifting unit automatically changes up a gear when the revs reach 6,800 rpm--about 200 rpm shy of the redline. As with all of its new models in recent times, Audi has given this latest S4 a nominal 40:60 front-to-rear apportioning of drive power.

Still no word on the price?

Looks dull in white,give that gorgeous blue one

Audi has hit the jackpot with this great new 3.0T.

I recall seeing the price for UK market in the Autocar test. Not 100 % sure though.

Great car...!! But with a soooooooo boring front

It's going to be about £36k in the UK, so less than the B7.

Here in germany, the prices begin at around 51.000 € (regarding the AMS - you can find it on the scans of the A6 3.0 TFSI test)!

I think people will definitely miss the rumbling V8 sound.

6 or 8 cyl, i was never interested in S4... Show us the RS 4, that's what matters!
