Only way I see that is a steep fuel tax. Maybe a displacement tax. Anything over 3.5L gets say $1.5k per L sales tax anytime title is transferred.
Strongly disagree, a displacement tax is not rooted in fact.
GMs 5.3 and 6.2 V8's are very close to the 3.5 V6 EcoBoost in EPA testing, but are better than the EcoBoost when towing in real world conditions.
Small engines have their use case, as do large displacement engines. If the goal is increased fuel economy, then tax that directly.
