Model 3 is a midsized four door car with a conventional trunk.
RAV4 EV is a "compact" SUV (to not be confused with a Chevrolet Sububan, which is a HUGE SUV), with a really generous storage area.
It also has ground clearance for those pesky curbs that you might accidentally drive over.
If they were both gasoline powered, nobody would compare the two cars.
Compared to a LEAF, the RAV4 EV is an improvement in almost every measure:
1) RANGE - 84 / 107 miles for a new LEAF at 65mph, and 140 miles for the RAV4 EV with a new battery.
2) BATTERY DEGRADATION - LEAF has a battery that is not temperature controlled, and without much surprise, the results aren't good for cars in hot areas. RAV4 EV uses a cooled and heated Tesla battery which handles degradation quite well. That means that I predict around 15-20% fleet average degradation at 100,000 miles, so a RAV4 EV can still go about 100 - 120 miles. Most LEAFs will lose far more range, making an 84 mile car become a 40-60 mile car.
3) UTILITY - it's no surprise that RAV4 wins over a LEAF. You can easily add a trailer hitch / bike rack, and even a roof rack. At least one person has added the third row seating.
4) INTERIOR ROOM - big win for RAV4 EV
5) CITY SKILLS - probably close to a tie. Both cars have a respectable turning radius, and both cars are about the same length for crowded on-street parallel parking. I like the higher seating arrangement of RAV4 in town, where I can more easily see pedestrians.
6) POWER - the Tesla powered RAV4 EV would eat a LEAF for breakfast
7) REPAIR COSTS - normal body repairs would be far simpler and cheaper on the RAV4 (there are millions of 2006-2012 RAV4 in the world). Only a small number of parts are unique:
a. outside mirrors
b. goofy rear wind deflector
c. headlights
d. front facia
Almost everything else is straight off the 2012 Toyota RAV4 Limited (gasoline car), including the Yokohama mud and snow tires. They left off the wheel flares, roof rack, leather interior, front tow hook access, and rear spare tire (the actual rear door is from the RAV4 Sport).
8) MAINTENANCE - RAV4 EV is a real turd, compared to the LEAF. Keep it under warranty!!!
9) DEPRECIATION/ OWNERSHIP COSTS - provided that you keep the Toyota Platimum extended warranty, the RAV4 will have a far lower cost of ownership overall from a new vehicle, compared to a LEAF. As you saw with $25,000 - $30,000 RAV4 EVs on the market, I can tell that a 2011-2012 LEAF can be purchased for under $10,000. With Nissan about to release a 200 mile LEAF, and other 200 mile range cars on the near-term horizon, I only see the current LEAF going down in value.
10) RECHARGE TIME - while any LEAF or RAV4 EV can easily charge overnight, LEAF has a huge advantage with DC quick charging in areas that have CHAdeMO stations. There are about 11,000 of these charging stations now throughout the world in Japan, North America and Europe. Our company solved this problem for the RAV4 and now it can also charge and CHAdeMO stations:
