Mach-E Thermal System Part 2: A Detailed Comparison to the Model Y

Tesla's manufacturing has come a long way in the past few years. In 2018, Sandy Munro famously tore down the new Model 3 with a lot of criticism for things like their excess of parts, fasteners, and welds. They made a lot of changes, including some he suggested, and now Munro tends to rave about how well they're engineered for ease of manufacture. This is a guy who gets paid by Big 3 auto companies to help improve their manufacturing. A great visual is this video of someone snapping together much of a Model Y like legos, in ten minutes by himself: [LINK] Another fun one is Munro's comparison of the thermal management systems for a Model Y and Ford Mach-E: [VIDEO]

> The problem is that driving EVs in the cold costs a lot more energy. I've got a Ford Mustang Mach E Nowadays this problem isn't "EVs," it's mostly just the Mach E. The Mach E delivers heat in the most inefficient way possible: resistive heat[0]. Modern EVs from other manufacturers use heat pumps, which are much more efficient. There's still some drop in winter range (like gas cars), but it's nowhere near 35% anymore.[1] Ford's system is also Rube Goldberg[2]: they use a water-based PTC heater to warm a small isolated coolant loop (complete with its own separate reservoir!), and then they run a pump to send it through a liquid-to-air heater core. Obviously done for commonality with an ICE heater core, but the unnecessary weight and complexity shows the compromises to shoehorn an electric drivetrain into a ICE (or "flex") platform.

Clearly you are not going to be convinced because you came into this conversation with a conclusion and backtracked from that just like the other poster. That is a common problem when discussing both Tesla and Apple. Both companies evoke a lot of emotion and "foaming at the mouth" type responses. Both companies have continued track records of producing stellar engineering. But for anyone else reading this try to separate your emotion for "lord elno" and just let the engineering speak for itself. [1]: [VIDEO] [2]: [LINK] [3]: [LINK]
