Omnis e-GT very disappointed

I recently purchased the omnis E-GT and im finding it lackluster at best. For an A class its got terrible top end (133mph) and slow acceleration. The primary advantage electric motors have over combustion is instant power delivery. The e vehicles should have significantly faster and smoother acceleration then a gas vehicle.

Also not sure if I missed somthing but I thought the winter package came with some pre installed custom modifications like paint. Mine showed up plane Jane and white.
