Forged amooth faced alloy wheels, with just enough tire for grip (195-215 width at max)
Use modified LEA Ecotec (2.4L), 12.5:1 compression, high flowing intake and exhaust manifolds... run it on E30 fuel(95oct)
Run behind this engine a GM F40 six speed transmission, 3.55 final drive and a pretty tall sixth gear... fit it with the factory Quaife LSD
Use this powertrain to drive the rear wheels
Package the width of the car small enough to just encapsulate the occupants(staggered seating) and keep the rear width small for shorter axles(more torque to ground)
Done right the curb weight should land right under 1000kg, CdA should be great and it, with about 210whp/215wtq, should be properly quick and fast... the gearing and CdA, coupled with lean burn on an ethanol fuel should see mileage with “normal” driving in the mid forties and with an experienced hypermiler at the helm, could be as much as 60mpg

G1 Honda Insight with a K20 swap. All aluminum, seats two, has a spartan interior, weighs under 900kg dry even after the motor swap. Innovative sells mounts and axles for it already so it's not horribly difficult. I've seen as much as 170ft-lbs of torque and
270HP to the wheels with a stock block, naturally aspirated; 230-250 is easy and reliable with a completely stock engine.
With a 6 speed Accord transmission (bolts on) or perhaps just the Accord's final drive swapped, 50-60mpg with conservative driving is not unrealistic on 87 octane.
Seats two comfortably side by side, lots of cargo room in the rear. It's wrong-wheel drive of course.
I can't imagine your GM variant being 1000kg, seems way too high for what it is.
