2011 Volvo S60 R-Design
Following in the tracks of the all-new Volvo S60, Volvo Cars' chassis experts are now taking the next step on the road to car enthusiast paradise. The result is the Volvo S60 R-Design - even sportier, even more dynamic and even more exciting.
"Refining a chassis is a bit like being an athlete looking to break new records. Once you're beaten one record, you're immediately focused on the next. In the R-Design chassis we've sharpened the steering, the agility and the solid overall impression still further compared with the dynamic chassis in the all-new S60," says Paul Welander, Senior Vice President Product Development at Volvo Cars. He adds:
"The driving experience should be so connected and compact that it feels as though the car has been milled out of a single block of aluminium."
After developing the all-new S60, which is Volvo Cars' most dynamic model ever, the chassis team focused on further refining a number of details.
"The challenge was to boost the dynamics without making the chassis feel raw. If the chassis is too firm, even smooth tarmac can feel bumpy. We wanted a distinct yet plush feel." relates Paul Welander.
Strut brace gives more direct steering feelThe chassis team fitted what is known as a strut brace under the bonnet, that is to say a bar that ties together the suspension strut towers. This is a classic method of stiffening up the body structure. The car now has a more solid feel to it, which in turn helps make the steering feel even more responsive with a distinctive contact with the road.
Monotube damping at the rearAt the rear the S60 R-Design features monotube dampers. Unlike the twin-tube dampers previously used, the monotube system features compression and return damping via the same valve. This gives shorter, faster fluid flow, which in turn means the damper responds more quickly. This higher operating speed takes care of the initial roll tendency that can be felt just when turning the steering-wheel. It's an effective way to improve the response and the connected feel.
Shorter, stiffer springsThe front and rear springs have been shortened by 15 mm to give the car more attitude. What is more, spring stiffness is 15 percent higher compared to the dynamic chassis in the S60.
"This makes the car easier to control and reduces any tendency to lurch. This is an area that requires true fingertip sensitivity in order to find the right blend of dynamics and comfort. If you go too far the car feels bumpy even on smooth surfaces. We've invested a whole lot of time and effort in finding the ideal balance," says Paul Welander.
Even firmer bushingsThe bushings with which the rear dampers are attached to the body are 20 percent stiffer compared with the dynamic chassis in the S60.
The front tie-blade bushing, that is to say the attachment in the rear of the car, is a massive 400 percent stiffer than before to counteract wheel bouncing and shaking.
"The stiffer the bushing, the less oscillation and roll. Movements are more controlled. This is clearly noticeable inside the car," says Paul Welander.
The new Corner Traction Control system provides even smoother progress in curvesJust like in the standard version, the chassis in the S60 R-Design is backed up by a range of electronic systems that sharpen the sporty driving experience still further.
Corner Traction Control is a new feature that uses torque vectoring to make for smoother cornering. The technology is a further refinement of the DSTC anti-spin system.
When taking a curve, the car's inner wheel is braked so more power is transferred to the outer wheel. This gives the driver a tighter line in the curve, with reduced understeering tendency.
The DSTC (Dynamic Stability and Traction Control) system has several functions that improve driving and safety properties, such as:
Advanced Stability Control. With a new gyroscopic roll-angle sensor it is possible to identify any skidding tendency at a very early stage. This means that the anti-spin system can deploy faster and with greater precision. Advanced Stability Control provides a huge improvement in driving properties and in emergency avoidance manoeuvres during dynamic driving involving considerable lateral forces.
Engine Drag Control. Prevents the wheels from losing their grip during engine braking on a slippery surface.
The DSTC system also has a sports setting that makes it possible for the driver to drive more actively. By disabling the anti-spin function, the car allows more pronounced oversteer.
In the United States, the Volvo S60 R-Design is available with a choice of two turbo engines: the six-cylinder T6 with 300 hp and the five-cylinder T5 with 250 bhp.

Elegant estate coupe car design technology presented on this official image gallery new 2011 Volvo V60 in metallic paint color exterior design. You simply have to drive this modern city sedan car to appreciate how we have driven chassis development to its pinnacle.
Sophisticated luxury car combine with comfort interior design. Volvo’s new sports car wagon is available with an option of two chassis. When cornering, the car’s inner driven wheel is broken, causing more power to be transmitted to the outer driven wheel. The sporty interior of the new Volvo V60 is also the most advanced high-tech environment ever available to a Volvo driver.
2011 Volvo V60 come with new innovation features Advanced Stability Control technology. Detail specification reviews, tuning car performance are available on first test drive vehicles report. The car engine’s power is delivered to the wheels using Volvo’s second-generation six-speed automatic Gear tronic transmission.
he 150 horsepower engine presents 240 Nm of torque. Both turbo diesels are obtainable with a 6 speed automatic car transmission otherwise six-speed manual gearbox. The initial annual target for the new Volvo V60 is 50,000 cars. The new Volvo V60 is built at the Volvo Cars production plant in Torslanda, Sweden.
