The highly anticipated Volvo S60 Polestar performance concept made its world premiere on Saturday on the sidelines of the Gothenburg City Race in Sweden.

The first thing you will need to know about the performance version of the S60 is that it is a one off model developed by Volvo Cars Official Motorsports and its racing and tuning partner Polestar for an as of yet unnamed client.

However, there's a ray of light for those that are gawking at this concept as the two brands stated that "a small series of Polestar modified S60s may be built pending market response". So in other words, if you like it, let the company know it. You can start by our comments section...

Now, to the juicier details of the S60 Polestar starting with the powertrain. While some sources believed that it may use the XC90's Yamaha-built V8, Polestar based the car on the S60 T6.

The regular model is motivated by a 3.0-liter turbocharged inline six delivering 300hp (304PS) to all-four wheels for a zero to 100km/h (62mph) sprint time of 6.1 seconds and a top speed of 250km/h (155mph).

The Swedes, however, made a whole lot of changes to the inline-six including modified cylinder head, combustion chambers, inlet manifold and air intake along with a larger Garret 3171 turbo, and as a result, the engine produces 508-horsepower at 6,500rpm and 575Nm (424 lb-ft) at 5,500rpm.

Polestar then lowered, widened and reinforced the chassis and also tuned the Haldex all-wheel drive system and Öhlins suspension and fitted the car with bigger Brembo brakes. Power is channeled to the wheels via a 6-speed manual gearbox.

The company quotes a 0 to 100km/h (62mph) sprint time of just 3.9 seconds and a top speed in excess of 300km/h (186+mph).

By comparison, the current Mercedes-Benz C63 AMG that is powered by a 451hp (457PS) 6.3-liter V8 hits 100km/h in 4.4 seconds and tops out at 250km/h (155mph - electronically limited).

On the outside, the S60's body was widened by 20mm on both ends and features a styling kit comprising flared wheel arches housing 19-inch rims in 265/30 R19 tires, a new front bumper with a splitter, side skirts, a discreet boot lid spoiler and a new rear bumper with a diffuser.

As for the interior, the performance S60 gets Polestar designed sport seats with increased support, Alcantara on all functional areas such as the steering wheel, gear knob, and seats plus a lowered center console lowered for improved gear-lever ergonomics.

Robert Dahlgren, Volvo Polestar racing driver, commented after taking the car for a spin:

"To me the Volvo S60 is a very well sorted car from start. In our concept car we have developed chassis, engine and transmission just like we want it, and the result is a huge leap forward in terms of handling and performance. It is, by far, the most impressive street Volvo I’ve ever driven. But I must also say that the genuine Volvo feeling is still there."

Thanks to Carlos A. for the tip!

So the Polestar version is pretty bad ass, but going back to the start of the article, can someone explain to me how the base model has 300hp, AWD, a six speed, and still takes 6 seconds to get to 60?

Is there a FWD version too? That sounds right in terms of times for a FWD model.

I'd really like to see Volvo get back into the game. I do like the styling of their new cars.

I'm wondering this too. Weight? Gearing?

Weight (at about 3600) shouldn't be the issue. The Infinity G coupes are hitting faster times than that and they're only RWD. Hell, the STI goes under 5 seconds with the same power and weighs only a little less.

The only thing I can think is that the older S60Rs (with auto trannies, mind you) were torque limited to keep them from grenading the gear box. Maybe it is the same thing here?

This is something that will bother me until I know.
Funny you should mention that. I was thinking the same thing because I was using your old Mazda as a comparison. (thinking it got to 60 in less time and was FWD with less power). Your Mazdaspeed3 had the same torque limitation in first gear too if I remember correctly.

I would think it was odd to do that with a sport model of the vehicle but then again the Mazdaspeed3 had it so hell it's possible I guess.

Could be longer gears, too. Besides 1st taking longer to reach its redline, if the 1st-to-2nd gear ratios are long, it could fall out of its powerband. 3600lbs. is pretty damn heavy, and should be used to account for a slower time.

Something like this has to be happening. I saw the same thing, when I was looking at Volvos. I decided not to get them because they seemed really slow, even though thier hp/tq numbers would prove otherwise. It does bother me though and I would love to know what's going on. Is anyone a member of the Volvo Forums?
