2011 BMW 528i: Throttle Tip-In Insanity
April 20, 2011
I drove our long-term 2011 BMW 528i the other night for the first time in a while. I switched back and forth between the Normal, Sport, and Sport+ settings. We all agree here that Normal setting is too lethargic with regard to powertrain response, so we'll forget that altogether. However, many people here like the Sport setting. But for me, this too has the familiar combination of sluggish throttle tip-in, followed by wild acceleration.
So Sport+ must be the place, yes?
The accelerator pedal feels stiffer in Sport+, as if the throttle return spring rate was increased. It's difficult to smoothly tip-in the throttle. And in Sport+ the throttle is jumpy, the transmission is jerky, and there is too much engine braking as the transmission tries to hold a low gear.
If I sound too fussy, I'll once again state that our long-term 2011 Hyundai Equus is just fine for me. The Equus' powertrain is much more refined, while still remaining adequately exciting (in Sport mode.)
Yeah, this isn't a straight up comparison as the Equus has a 4.6L V8, while the BMW has the normally aspirated 3.0L inline 6.
Whatever, they're both executive sedans that cost about $60K.
The bottom line is if you told me five years ago that one day I would prefer the powertrain of a Hyundai to any BMW, I would have called you insane!
