It’s bigger. Does that mean it burns more fuel or has more emissions than a 40 year old car? I’m all for saving the planet, but I’m not sure big automatically means worse. I could be wrong.
They are still gonna be less effecient than smaller, lighter models with modern technology.
Agreed and I’m sure bmw makes smaller models, so this pic is rage bait.
Another factor is bigger vehicles are deadlier.
Deadlier for whom? My guess is the passengers of a bigger vehicle are safer. A pedestrian being hit by a small car or big car is likely ruined either way. An SUV hitting a small car, maybe the small car’s passengers are in trouble, though perhaps advancements in safety have increased survival, idk.

Vehicle size actually has a huge effect on the severity of vehicle-pedestrian collisions.
I find that full-size SUVs and pickup trucks pose a particular danger for pedestrians.
A pedestrian hit by a full-size SUV is twice as likely to die than a pedestrian hit by
a car under similar circumstances, while being hit by a pickup truck rather than a
car increases the death probability by 68%. I find that high-front-end vehicle designs
are particularly culpable for the higher pedestrian death rate attributable to large
vehicles. A 10 cm increase in the front-end height of a vehicle increases the risk of
pedestrian death by 22%.
The small one is an E30 3 series and the big one is an X7 (pre-2022). The X7 does get slightly better fuel consumption than that, 27-29 mpg on the petrol engine. The 3 series is probably somewhere in the low 20s based on forum posts but I’m not sure where to get actual data for that one, and I’ve got no idea which engine is in it
Bigger does almost always mean more emissions/worse economy for a given technology. In this case someone else pointed out that the economy is about the same for both, which is due to the fact that technology has improved; if you put the engineering effort of the big car into the form factor of the little car, it’d be much more efficient.
It weighs more and definitely could use a lot less space on the road and costume less fuel if it didn’t grow to this size but stayed small and with less weight
They’re bigger specifically so they can qualify as “light trucks” instead of regular vehicles, which means they have more more lax emissions standards.

Source study.
I stand corrected. Appreciate the data. Thanks for educating me on that! 👍
The people the driver of the bigger car cannot see.
And also people in a smaller vehicle involved in a collision. Higher bumper heights hit windows instead of crumple zones.
Fair. Tech (sensors, cameras, etc.) could reduce this risk, but you make a fair point.
Better road design and just having fewer cars would do a lot more than sensors.
the 1984 BMW 318i gets 24 mpg the 2024 BMW x7 gets 24 mpg
Thank you for sharing actual data 🤝
i was guessing the actual models pictured, anyone know better?

BMW does offer small models tho. This pic is comparing apples with oranges.
means it’s easier to claim you didn’t see the kid you just ran over

I replaced my old Ford Focus stationwagon with a Nissan Qashqai, an SUV. It has much better milage so it’ll probably have less emissions.
