Part 2;Cars in the EU getting better MPG than cars in the U.S.?

Question

Thanks all for your Answers.

Yes, there are a number of “factors” about EU vehicles that give them better gas mileage than U.S. models.

Diesel, smaller vehicle (lighter), and smaller (less horsepower) engines, are obvious “Answers.” But, there are plenty of Petrol vehicles (96 get 41-46 MPG) advertised at uk.yahoo.com

Gallon being different, MPG estimated differently on the Window Sticker, and more strict emissions in the U.S. are real Answers.

Driven shorter distance, at a different “pace,” less safety standards (thus lighter), willingness to drive less powerful-smaller cars, price of gas, taxes, and better tuned are personal “speculation,” (not Facts) and have nothing to do in advertising MPG.

MPG is MPG.

Let’s pick a similar car at random from UK and U.S.

BMW 1 Series

U.S.

128i

230 hp

28 mpg

UK

125i Petrol

218 hp

35.8 mpg

Did anyone even read my questions?

Answer 1

The biggest factor causing a difference in hp and fuel consumption between EU and US vehicles  the excessive smog and safety regulations imposed on cars sold in the US.

EU cars brought into the US must be specifically designed for the US market, or must be retrofitted with smog and safety features (Grey Imports).

Anytime you increase smog equipment on an engine, and increase weight with additional safety features, there is a loss of horsepower and rise in fuel consumption.

Answer 2

Ford,G.M. and Chryslers for years have built little diesel cars.Some getting 72 mpg and reaching speeds over 110 mph.However they are not fast of the line.People here like to race everyone,and these makers think they would not sell.I'd love to have  a real german diesel Smart for 4.

Answer 3

if yo were paying over 8$ for petrol per gallon, you wold drive more efficiently also.

Answer 4

No, I didn't read your other question.   But the part about an imperial gallon and a US gallon sounds reasonable.   A litre is larger than a quart.   4 litres is almost 1 quart more than 4 quarts.   That's probably a part of why they get better mileage, but probably not all the reason.

Answer 5

The EPA also retarded the ignition from 14 deg TDC to 10 deg TDC...

Answer 6

The US just this year changed the rules on how to compute the MPG that automakers are allowed to report.  The new rules have lowered the MPG of all autos in their advertised MPG.  I have no idea how the European rules compare with the US rules, but that may explain some of the differences.
