The idea that we’ll someday be able to control the weather still seems relegated to science fiction. Maybe the next best thing is helping a car drive more safely in poor weather – and more
enjoyably in all driving conditions. That’s what the 2011 Volvo S60 does.
Today’s younger drivers might
not remember a time when, if there was snow on the road, your car’s drive wheels
might slip and spin, and the car was not able to move. The introduction of
traction control about 20 years ago helped considerably. A more recent
development, stability systems, helped to reduce the potential for sliding on
dry or slippery pavement, especially when driving through curves. Along the way,
more carmakers adopted all-wheel drive to help cars get through just about
anything on the road.
As it has in some past
models, Volvo brings all of those technologies together in the 2011 S60. Now,
however, the technology is more advanced than ever and is combined with Volvo’s
three choices of chassis tuning for the S60 - “Touring,” “Dynamic” and “FOUR-C.”
That choice allows the S60 driver decide how the car rides and handles. In all
cases, the new S60 is simply more fun to drive than before while providing even
greater dynamic safety performance.
The “Touring” chassis provides responsive handling while
emphasizing a smoother ride on rough surfaces. The “Dynamic” chassis essentially
tightens up steering and uses stiffer springs, bushings and dampers (shock
absorbers). “You simply have to drive the car to understand, preferably on a
narrow winding country road where every sweeping bend brings a new challenge,”
says Stefan Sällqvist, who is in charge of S60 chassis development. “That's
where the all-new S60 comes into its own and shows off its agility.”
Customers can also specify
the “FOUR-C” active chassis for the 2011 S60. This system uses advanced,
self-adjusting dampers to respond – in fractions of a second – to the road
conditions and the driving situation. The driver can select the car’s ride
character from three available modes - “Comfort,” “Sport” and “Advanced.” And
here’s a piece of trivia sure to impress at dinner parties (or not): Volvo
tested its new chassis tuning on old Roman roads in England, which have received
only a few layers of pavement over the centuries.
Whichever chassis setup the
S60 customer chooses, the car is designed to grip the road with remarkable
tenacity. That’s where the big guns come in - all-wheel drive, Advanced
Stability Control and Corner Traction Control.
Volvo's all-wheel drive with
Instant TractionTM, developed with all-wheel drive expert Haldex, is
designed to ensure the best possible road grip whatever the situation. As you
would expect, the system automatically distributes power between the front and
rear wheels. When you need a burst of acceleration, the Instant Traction
function shifts power from the front to the rear wheels at lightning speed. The
extra power at the rear wheels works in concert with the natural weight transfer
of a car under acceleration to maximize rear wheel traction. The system works so
smoothly that the driver and passengers do not even feel this occurring.
Working with the all-wheel drive is an enhanced version of Volvo’s Dynamic
Stability Traction Control (DSTC) system, which incorporates new Advanced
Stability Control – the first sedan on the market to do so. That’s a lot of
lingo. Here’s what it means for you: the system can now detect and correct
conditions that might lead to skidding or sliding even before any such
hazard arises.
Not only does Advanced Stability Control help make the S60 a safer-driving
car, it also contributes to driving enjoyment. That’s because it allows more
dynamic driving (sharper cornering) while acting as a kind of electronic
watchdog for the conditions that might spoil the fun.
Speaking of cornering, the S60 debuts a new technology for making cornering
smoother and more precise. Corner Traction Control uses what engineers call
“torque vectoring,” something turning up on the world’s best sportscars, too.
When you drive through a curve, this system can transfer more power to the car’s
outer drive wheel. “This system makes it easier to smoothly maintain your
desired line on winding roads and on wet surfaces,” says Volvo handling expert
Sällqvist.
Come the Fall, you’ll be able to put all this technology to the test. Make it
a point to test-drive the S60 – before the bad weather sets
in.
