Comment on SUVs emit more climate damaging gas than older cars do, study finds
paintbucketholder@lemmy.world 8 months agoI never said there’s no new technology because there is
Well, alright then: what is the new emissions reducing technology that 2023 SUVs have, but smaller 2013 cars don’t have?

Better fuel management in general? More forced induction engines than before? Improvement on existing tech? New emission control equipment like DPF, SCR (that thing that made the difference between cars that only required a retune vs cars that required a buyback/mechanical modifications for VW diesels)?
Do you think manufacturers have been using the same engines and fuel injection methods since the introduction of OBDII or something?
Smaller cars can also get by without things like direct injection because they don’t require as much power to get going, but under constant load (on highways) it means worse control over fuel injection vs more modern tech.
