That will increase size of battery, so battery packaging is non-trivial. Current PHEVs in smaller, lighter vehicles achieve 20 - 40 miles all-electric on batteries in the 18 - 25 kWh range.
Assume it’s an EREV:
BT1 is probably your starting point. Battery and electric motors are already packaged. You don’t need a transmission or driveline. The exhaust and fuel tank are simplified compared to a PHEV and so they’ll be smaller. The engine is the main issue for packaging. Remember that frunk in Silverado EV? That would be gone or significantly reduced. The 200 kWh battery becomes a 100 kWh battery. That should free up enough space for a small (10 gallon or less) fuel tank.

Is the 80% of commuters driving less than 40 miles a day still accurate?
Auto reporting sites rarely makes the distinction of different plug in styles.
-PHEV should fulfill a buyer cost benefit.
-A small tank or engine in a BT1 EREV would be a like malaise-era choice. It's power should be made to be sustained over a large tank.
-High battery range regulation stacks the deck against plug-ins. The engine is an asset that should see use.
