Saw a video about this yesterday.
Unimpressed.
What good is a turbo I-4 with hybrid assist for 400# of torque if the battery is only good for 2000 watt-hours and the electric motor puts out 15% of the total max horsepower, and probably 25-35% of the total max torque? A 48hp electric motor (probably offering between 80-100# of torque) is going to chew over 30,000 watts per hour in operation at max load. Don't try and tell me the turbo I-4 has the torque, because it doesn't.
The electric assist motor is only good for about 4 minutes of climb and then it's discharged its battery entirely. Unless the ICE can recharge that battery promptly... not via trickle of the alternator's spare juice at maybe 500 watts an hour (4 hours to charge it)... then you get one good hill climb out of it and it's spent for the rest of the drive.
This I-4 couldn't tow 6000 pounds from Phoenix to Show Low (lots of elevation gain), but it could probably do Phoenix to Tucson (all flat).
