Is there anything apart from the Champ style ones as they don't have seats in the back or only a small one

 

Would prefer a gasoline version of this as don't want the hassle of charging.

 

Just don't think this will be fast enough as it's maximum speed is 25kph and might as well buy a tandem. 

 

These would be great if you could do around 50kph with 2 people unless someone knows of a quicker onE

 

Don't need to be drifting out of bends leaving rubber all the way part 7/11 but need a bit more power.

The only Champ vehicle i see is this type which is gasoline but has no seats at the back and don't really want to buy the EV type as heard they struggle with 2 people and struggle to get 25kph

Tuk Tuk would be ideal but pricey
