* Completely obliterate the front end: The engine, chassis, and passenger compartment would be crushed beyond recognition.
* Potentially cause the car to disintegrate: High-speed impacts can generate forces that exceed the structural limits of the vehicle, leading to fragmentation of the car's body.
* Result in a massive explosion: Depending on the fuel type and the integrity of the fuel system, a fire or explosion is highly likely.
In short, the result wouldn't be a compact anything; it would be a scene of extreme devastation. The energy involved is far too great for the car's structure to withstand.
