RAM canceled the huge battery version that was to have a range of 500 miles. The version with a smaller battery will still be made but the RAMcharger will be built first.
The VW EA888 2 liter is a good motor. The biggest issues are a leaky water pump and carbon buildup from direct injection. I don't know anything about the reliability of the 1.5 TSI EVO engine. These are 2 likely candidates and both are made in Mexico.
Dual-motor Rivian 0-60 is 3.4 seconds. That's comparable with a dual-motor Scout. The Tri-motor Rivian is $20k more and starts around 100k. The quad-motor is over $110K. Performance comes at a price. `Scout will not be a boring vehicle.
If EV's do achieve cost parity in the next few years, there should be no reason for EV incentives. Money is better spent upgrading our electrical grid and charging infrastructure.
It's pointless to worry about things we can't control. We'll have an idea of pricing in 2 years. Many experts predict EV's will achieve cost parity with ICE vehicles by the time Scout is for sale. If the batteries come from Canada and the Harvester engine from Mexico, then prices will rise...
