I just don't get the CR bashing here. The Model 3 is prominently displayed on the front cover this month! As they made it one of their top 10 vehicles of 2020, saying that the manufacturing issues are behind them. IMO they tell it like it is more fairly than anyone else, and no I don't agree that they put their hand on any scales. They praise things and they ding things, like they do on every other car they rate. Maybe they just use different scales than you would like? Let's keep in mind their mission, which is consumer protection, not automotive enthusiasm, so they care much less about performance or wow factor than they do safety and value. Their target audience are safety-conscious consumers looking for the best vehicle to get them from point A to B with minimal fuss or learning curve. That's why they downgrade autopilot and touchscreen-centric controls - too hard for grandma or a teen to use safely.
They don't go down to submodel on any vehicle, likely because they don't have that kind of budget. No advertising, so they have to get by on magazine/online subscriptions. They anonymously buy each car they test, as they don't accept cars from manufacturers. So no A4/S4/RS4 or 911/4S/turbo split out either. I was actually surprised they bought a Model S and X a few years ago, as typically they stopped around the 5-series / E class price level.
As for the Model 3, they gave it a 98 for driving experience. What's to complain about that? They dinged it for a bit of a rough ride, and my Model 3 owning colleagues at work all agree that that's true, especially compared to a Model S air suspension. The reliability issues they point out in their surveys on both cars align with complaints here on this forum and my own experience on the Model S. My Tesla isn't screwed together nearly as well as my 2010 Lexus nor even as well as my old 2001 Saab 95. Consumers today demand more than just a car that doesn't break down - they expect the paint to be blemish-free, the interior trim to not fall apart, and the audio controls to not be glitchy even on the cheapest vehicles, so CR follows the times and considers them reliability (though they do give more weight to major systems like engine/tranny/steering/brakes when rolling up scores).
