Yes, this is what I have been told as well.Yes, part of that is true.
The later 500Es and all facelifted (i.e. E500s) were brought back into the MB fold to eliminate the logistical nightmare and associated costs. This occurred at about the same time the 400E/E420 became a production vehicle.
True. When you crawl around one you start to see lots of areas that Porsche got their hands on. There is much more done to these chassis than just finding a way to get the M119 in. One interesting aspect of a 500e compared to a 400e is that although the transmission tunnel was expanded on both cars, Porsche apparently left more room for the driver's feet. In my 400e I continually scrape the left side of my shoe on the brake pedal when coming off the throttle but that never happens on the 500e. Both are '93. Another difference is additional sheetmetal in the spare tire well. So there are the obvious mods Porsche did and there are the not-so-obvious mods too.Porsche used to modify the chassis to hold the new drivetrain. Car was sent back to MB for paint, and up you go back to Porsche for complete assembly.
Porsche was in a bit of trouble in the early 90s and one reason was that the UK economy was crumbling (again!!!) and the city guys weren't buying their usual quota of 911s. Porsche needed work and this was a sub-contract opportunity with the stronger Mercedes who had diversified into the lower cost 190 series and were able to weather the storms of recession by having a broader client base.
.Whatever mods Porsche did is reflected on the way the car handles when driven hard. I can't explain in words how the 500E rides better than the SL500 beyond 100MPH.
That Audi was an RS2, which out-accelerated the 500E. But these two were really world's apart in their approach and appeal; not really an either/or choice to me. I consider each to be just about the most desirable limited-run vehicles from their era.Porsche was also working with audi.
I prefer the mb
A car company can make any car fast. Once you get past your boy-racer yrs though, it takes more to satisfy most of us. The 500E has it all for a sedan; performance, grace, space & aplomb....the personification of a tour de force.No comparison at all. They each scratch a different itch.
