Climate Change -- conspiracy theory or is it time we all drive a Prius?

This Bugatti Chiron has 12 cylinders and displaces 8L. It costs $3,825,000 and there are just 9 of them .

Quote: By Joel Patel February 23, 2022

Top-speed runs are making a comeback, as automakers have made massive strides in powertrains and aerodynamics. Like lap records, top-speed runs are purely for bragging rights. There’s no incentive to having one of the fastest cars in the world beyond giving automakers the ability to say that they have one of the fastest cars in the world. It really is that simple.Unlike other figures that are used to differentiate vehicles from one another, like zero-to-60 mph times, cornering G-force, or quarter-mile times, setting a new top speed record is insanely difficult. Beyond ensuring that a car has the right amount of power and efficiently flows through the air, finding a long enough stretch of road to get a car up to 300 mph is nearly impossible. That’s why top speed records rarely get broken.
Horsepower still reigns supreme as the primary metric to compare cars against one another and for outright bragging rights, but the metric has lost its primacy recently. Family wagons now make 603 horsepower and three-row SUVs can be fitted with 710-horsepower engines. Year after year, automakers continue to raise the bar with even more powerful vehicles. A few automakers, though, continue to chase another, more rarified figure — top speed.
These vehicles are the fastest cars in the world. The majority of vehicles have proven top-speed records, while a few are claimed top-speed figures. Also, this list includes a few models that would set records if they were to go into production.

Looking at the relationship between number of cylinders and displacement for vehicles sold in the US in 2022 (except for exoticx)

# Cyl	Min		Max 	
3	1.2L   -	1.5L
4	1.3L   -	2.8L
6	2.7L   -	4.0L
8	3.8L   -	6.4L

We all know that most automakers are downsizing their engines to make them more fuel efficient. Toyota Division is getting rid of the last of their 8 cylinders although they sell some in the Lexus Division. The Toyota 4Runner is 4.0L 6 cylinder so it is on the top end of the 6 cylinder displacement scale.

Do you think there will ever be an outright ban on vehicles over 6 cylinders? Or displacement over 4.0L.

I have heard that larger L-4s are not the best idea. 500cc per cylinder is around ideal. Almost no vehicle needs more than a 4 these days, the market is taking care of it.

The 500cc thing is just something I heard. I’ve also always heard going too big can really affect 4 bangers. All kinds of balance things come into play.
