vibration issues.

Top Speed85 MPH (136 KPH)
Not sure the top speed but have easily hit 85.
AccelerationMuch better than stock, it's not a sports car
but it feels sporty.
Staring in:
1st Gear - almost useless because you have to
shift out right away
2nd Gear - Fun quick take offs that go all the
way to 40 or 50 mph
3rd Gear - Starting in 3rd feels like starting
in first with the stock engine
4th Gear - just for highway, really sluggish
to start in 4th
Range200 Miles (321 Kilometers)
Longest trip so far has been just over 100 miles
with over 4000 feet of elevation gain at highway
EV Miles
Start:54,750 Miles (88,092 Kilometers)

Seating Capacity2, there is still a back seat but do those
really count in an old Ghia?
Curb Weight2,300 Pounds (1,045 Kilograms)
The car is somewhere between 300-400lbs over
stock. This is mostly because of the 500lbs of
batteries for this build.
