Volkswagen has redesigned many aspects of the Polo's chassis with its McPherson front suspension and semi-independent rear suspension. For example, its track width was increased by 29 millimeters in front and 30 in the rear (new dimensions: 1,464 mm front, 1,456 mm rear). This has resulted in improved vehicle dynamics. Comfort was enhanced in parallel.
Improved directional stability
In front, Volkswagen has integrated a completely redesigned McPherson strut type suspension in the Polo. The front wheels were moved five millimeters forward to achieve a greater caster angle, and this offers greater directional stability. Furthermore, new strut bushes are used on the Polo; on the one hand they are lighter, and they also improve ride comfort. Larger wheels can now be used as well, and this further improves comfort. At the same time, these wheels have a positive effect on driving performance.
ESP enhances safety as standard equipment
The Polo is being sold in Germany and in many other countries with electronic stabilization program (ESP), including hill hold control, anti-lock braking system (ABS), braking assistant, anti-slip regulation (ASR), electronic limited-slip differential (EDS) and engine braking control (MSR) as standard equipment. Overall braking system performance was modified for the new generation Polo; among other elements, the 8.5 inch brake booster is being replaced by a higher performance 10 inch system.
With an eye toward attaining the goal of a five star rating in the EuroNCAP crash test, the steering column – with its continuously variable height and reach adjustment – was completely redeveloped. This redesign led to reduced weight. The standard electro-hydraulic power steering system was taken from the previous model and adapted to the new front suspension kinematics. Engineers developed entirely new tuning of the steering system. Steering feel and responsiveness as well as the center point – which defines steering feel in the straight-line tracking position – now set new standards.
