* I dug through my waking nightmare and did some internet searching.
* Length- 170.9-inches
* Width- 66.7-inches
* Height- 52.7-inches
* Cd 0.35 for the notchback
* Frontal Projected Area, ( Af ) not published, so using the Ford Tempo, who shares very similar W & H, @ 84.91% gross area, = approx. 20.726 sq-ft
* CdA = approx. 7.25428 sq-ft
* Curb Weight = 2,463- pounds
* EPA Test Weight = 2,763- pounds
* Length / square-root of Af = approx. 3.12826
* Engine = 65% energy loss, @ constant-velocity cruise, warmed, straight, level, dry, calm, no acceleration, no deceleration.
* Engine accessories = 2.2% energy loss
* A4 Overdrive Transaxle = 7.81% energy loss
* Regular Unleaded, Reformulated, E10 Ethanol = 111,836 Btu / gallon
* 3412- Btu / kWh
* 2,546 Btu / bhp-hour
* @ 60- mpg @ 55-mph = 0.91666-gallons/ hour
* 5.6264 -pounds/ hour
* @ 6.138-pounds / gallon, mass
* 13.2-gallons capacity
* 432.6597- kWh 'pack'

* The most interesting data from my archive has to do with the 1994, Euro-spec, Ford Mystique ( Mondeo / Contour )
* L- 176.4"
* W- 68.8"
* H- 54.0"
* Cd 0.31
* Af 22.06 sq-ft
* CdA 6.838 sq-ft
* L / sq-root of Af = 3.12978
* Curb Weight 2850- lb
* 1.989- liter
* Manual 5-speed
* 56-mpg @ 56-mph
* 45-mpg @ 75-mph
* 1-gallon / hour @ 56-mph
* 6.138- pounds fuel / hour
-------------------------------------------------------------------------------------
* Tracers 'bar-graph' is nearly identical to the Mystique, suggesting that if morphed into the Mystique shape, she'd reach Cd 0.31 with no added length.
--------------------------------------------------------------------------------------
* To get from 56-mpg, to 60-mpg, would require on the order of Cd 0.26, if you did everything with aero mods. And that presumes an equivalent BSFC as that of the Mystique.
--------------------------------------------------------------------------------------
* A 15- car average for Cd 0.26 cars yielded and average L/ H = 3.4226.
* Based on the Tracers Height, she would need an additional 9.463-inches elongation to have a chance at Cd 0.26, or 180.363"
* Tracer's L/W ratio for Cd 0.26 would be easily satisfied at a length of 180.363-inches.

A hard look at what an extended-length, Mondeo/Contour/Mystique would look like, would tell a lot about Tracer's body-morphing requirements, to get you in the hunt.
