When the E-Pace was first reviewed by the motoring press, it was mentioned that in the P300 with 20" wheels especially, the ride was firm. That was also before the adaptive dynamics option was available.
I was looking to go for the HSE but both the configurator and the sole Jaguar dealer here in Cyprus said that it wasn't available with 19" wheels. To my eye the 19" wheels are the smallest size that look good and the extra inch of tyre should help with the ride quality. So I opted for the SE with adaptive dynamics and specced it up to HSE standard minus things that I thought I'd not use like the gesture tailgate.
And I'm happy with the ride quality. What wheel size do you have?
