Outstanding Ride Comfort Plus Precise, Interactive Handling
A sophisticated all-wheel drive system coupled with low-friction, long travel four-wheel independent suspension and low-centre of gravity ‘boxer’ engines have all contributed to the Impreza’s reputation for outstanding chassis dynamics.
Now for the new model, Subaru has devised a completely new platform with a 3.7 ins (95 mm) longer wheelbase, tracks widened by around 2 ins (50 mm) and a sophisticated multi-link, double wishbone rear suspension.
In addition, to further improve handling and roadholding, the position of the ‘boxer’ engine has been dropped by almost half an inch (10 mm), lowering the centre of gravity still further.
Other changes include a quicker steering rack with more rigid mounting and new design of MacPherson strut front suspension. The result is a highly-absorbent ride with precise geometry control for accurate straight-line running over uneven road surfaces backed by extremely responsive steering and handling.
The rear multi-link, double wishbone suspension liberates more luggage space thanks to its compactness compared to the previous rear strut arrangement.
And because it is attached to a sub frame via bushes, with the mounting section moved to under the floor itself, road noise is reduced.
The rear springs and shock-absorbers are mounted behind the centre-line of the rear wheels, with the wheel stroke itself moving rearwards – all helping ride comfort. A rear anti-roll bar is fitted to the 2.0 litre Imprezas.
At the front, the previous sub frame has been eliminated, saving 20 kg in body weight yet a new box-section for the front cross-member provides the same level of rigidity. In fact, the new Impreza WRX five-door is a full 30 kg lighter than the previous Sports Wagon.
The new MacPherson strut and anti-roll bar layout is based on that used by the highly-praised Legacy. It offers high lateral rigidity which improves steering response and cornering stability.
This is further enhanced by a new design mounting for the steering rack. Furthermore, special suspension bushes and attachment points reduce road shock.
The steering gear ratio has been changed from 16.5:1 to 15:1 for a sportier feel while the rack diameter is increased from 23 to 26 mm. The result is a more linear feel to steering inputs. A new variable capacity power steering pump is used throughout to improve fuel economy. Wheel and tyre sizes have been optimised for each model’s suspension setting with the new Impreza 1.5R running on 195/65 tyres mounted on 15 x 6 ins alloy wheels and the 2.0R having 205/55 tyres on 16 x 6.5 ins alloy wheels. Finally, the sportier 2.0RX and 2.5 WRX boast 205/50 tyres on 17 x 7 ins alloys.All Imprezas marketed by Subaru (UK) Limited come with the reassurance of a three year or 60,000 mile warranty plus 12 year anti-corrosion cover and three year paintwork warranty.
This is in addition to three years’ membership of Subaru Assistance – a comprehensive home and roadside repair and recovery package throughout the UK and Europe administered by Mondial Assistance.
