et job/I picked up a copy of Consumer Reports, New Cars Best and Worst, Cars SUVs and Trucks. in the Road Test Highlights section the Ford Escape SE Sport Hybrid was listed. I was surprised to see 30 MPG city, 38 MPG highway and an overall 34 MPG for their fuel economy test MPG numbers. CR says the road test is performed at their 327 acre Auto Test Center in Connecticut but provides no information on how the MPG numbers are derived.
CRs MPG numbers are way off my experience. After 10 months (8,000 miles) my overall number is 45 MPG (per tank fillups range from 37.9 MPG to 48.8 MPG ). I live in MI so I expect my next tank or 2 to be below 40 MPG as well.
I certainly expect some variance based on weather, driving style and where someone drives but I never expected such a large variance between my numbers and CRs.
Does anyone know how CR comes up with their MPG numbers?
I subscribe to CR. I was very disappointed in their review of the 2020 Escape. I consider it a "hatchet job."
I have compared it to several of their other reviews; found it to be substantially different in both tone and the subtopics covered.
I also listen/view the CR video series Talking Cars, which had good things to day about the 2020 SE Hybrid, e/g/ "The Escape done right."
I recently received the CR Buying Guide for 2021
Ford Escape - Page 152: Hybrid Sport - Highs: Fuel economy; agility; stopping distance; controls.
Lows - "Can only get auto-up windows on Titanium trim."
Compare that with the listing on page 166 for the Toyota Rav4
Highs - Fuel economy
Lows - "Ride, fit, and finish."
Seriously. a lack of an auto up is more of a detriment than "ride, fit, and finish?"
But, as for your precise question---how do they come up with the numbers?
1) According to Talking Cars and the online reviews, they drive the cars.
2) A couple of times a year, they send us a survey. Who is "us?" Answer: Members.
And we tell them what we think.
According to what I've heard, CR members are generally liberal, generally love the environment (so love electric cars), and generally love foreign cars over domestic.
There is no scientific method. There is no objectivity. It's all opinion.
I'll add how my wife and I bought a Subaru for the symmetrical AWD. We live in New England; we wanted and need AWD.
CR raves over Subaru. So, we bought a Subaru.
They are nothing special. The typical rattles and little problems you find in any car---foreign or domestic.
Oh, the CD player mysteriously broke after a couple of years. Then CR reported this has been an ongoing issue.
The backup camera is unusable in bright light; it is small.
We got the winter package. We discovered the heated mirrors don't really heat; the defrosters aren't very powerful; plenty of ice buildup.
But, CR always loves the next model of Subaru. Just like it always loves the next model of Toyota.
To wrap up, I'll state how over the last year (purchased the hybrid 12/18/2019) I've averaged a solid 40.6 mpg and had no issues.
We love the car.
I don't trust CR as much as I used too.
Thanks for listening.
