Secrets of the new BMW 5 Series

Our friend Richard Aucock has recently completed a 24-hour trip from South France to Middle of England, aboard the new 2011 BMW 5 Series. While present at the 5 Series launch, he also had a chance to sit down with several key people involved in the 5er project. One of them is the BMW Group Driving Dynamics Director, Jos van As.

Let’s find out what he had to say about the new 5 Series.

“BMW Group Driving Dynamics Director Jos van As says it was owners of the old BMW 5 Series that led direction for the new one.

‘Feedback from owners of the old car was that handling impressed but the ride was too hard.’

This is why the F10 BMW 5 Series rides better than before. You notice it right away at low speed: van As admits they’ve used ‘quite moderate spring rates,’ giving the cushier, plusher feel.

‘Double axle front suspension also helps. We have more grip, so there’s more freedom to tune ride and handling. We have more possibilities to tune the dampers.’

There’s more: ‘Don’t forget, we’re now in the 4th generation of runflat tyre – the old car used 2nd generation. This is a huge jump. We have been able to optimise the tyre wall stiffness – this is a crucial point regarding how absorbent the ride is.

Ride on some more, too: ‘With the new car we have been able to choose a new tyre size, keeping inflation pressures on the healthy side. If you have a smaller wheel, you have a smaller air volume, therefore need higher pressures.’

    Interesting, “quite moderate spring rates” might mean that with the F10 the Electronic Damping Control, Active Roll Stabilizatoin options are now necessary to have the same handling I enjoy with my E60. Side note, this is one of the first photos I have seen with the shadow trim on the F10. Looks great!

    Some genuine reporting here, by Aucock. Unlike others who bluff. Tho, he’s helped alot by his relationship with Herr van As.

    Anyway, the R-R tie-in is a hint of what’s going on at BMW these days; no longer about specific platforms, all about *modules* now…including suspension modules.

    Yes Bob, Richard is great, always been. We’ll see him in two weeks for a BMW event and we’ll make sure to get more stories out of him as well.

    He’s a close friend.

    Well so long as they retain the great handling and performance, I have no problem with improved ride comfort.

    I purchased a new 550I recently and it is everything BMW said it was. Great versatility in suspension and transmission choices. Still not sold on the run flat tires and will put 20″ rims and tires to improve sport handling ability. This car is a winner and love the softer lines.
