Volvo S60 Polestar Enters Limited Production


Truth to be said, last year's S60 Polestar Performance Concept was a big success in terms of publicity for Volvo, with the one-off, 508-horsepower-strong sports sedan turning many heads towards the Swedish carmaker. To refresh your memory, said saloon was sold to an unnamed American collector for $300,000 or about €228,500 at today's exchange rates.
At the time, both Volvo and its official racing and performance partner Polestar had said that they were considering a limited production run of the car. To some extent, the two companies have made that happen.

We say "to some extent" because the limited production S60 Polestar does not have all the performance goods or the 508-horses of the concept, and for the time being, the 345hp (350PS) model will be offered exclusively for the Australian market. However, Volvo said that the new S60 Polestar was developed as a pilot project and that further markets "are under investigation" pending the response of the Australian launch.

"We received a fantastic response to our Volvo C30 and S60 Polestar concept cars, so we are very happy to now introduce our first production car to the Australian market," said Christian Dahl, Managing Director of Polestar. "This is an important step forward for Polestar, one that promises an exciting future."

What Volvo and Polestar did with the new car is take the standard S60 T6 R-Design and upgrade it with select parts from the S60 Polestar Performance Concept such as dampers from Öhlins, high capacity brakes, while also tweaking the car's aerodynamics with new kit including a front splitter, rear wing and diffuser.

Under the hood, the 3.0-liter six-cylinder turbo-charged T6 engine gains a bigger turbo, new intercooler, revised engine mapping and racing exhaust to lift output to 345hp (350PS / 257kW) and more than 500+Nm (369+lb-ft) of peak torque.

A tuned six-speed automatic gearbox transfers power to the road through an all-wheel drive system featuring modified software for more rear torque. Volvo says that the weight remains unchanged over the standard S60 T6 R-Design at 1,684 kg (4,176 pounds).

The S60 Polestar goes from 0 to 100km/h (62mph) in 4.9 seconds and has a limited top speed of 250km/h (155mph).

"The Volvo S60 Polestar is a car that we are truly proud of, our first step to a production car available to the customers," said Robert Dahlgren, Volvo Polestar Racing driver.

"We have taken the best bits of the standard S60 T6 and our S60 Polestar Concept Car, creating a vehicle that puts a smile on your face when you drive it over your favourite twisty road. At the same time, it is more than capable of everyday driving, too," he added.

Volvo S60 Polestar 508 HP



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.

 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."
