I suppose the answer to your question depends on your definition of "performance." My car does a good job at going slow I get 32mpg and have a range of 650 miles between fillups. For my purposes (commuting 80miles/day) this is excellent performance.

In terms of speed, the car is a little slow getting from 0-60...but I think it has plenty of power for cruising between 65-80mph. If you want to go faster you might consider a different car.

The 95E300D cannot be "chipped."
