Currently, Tesla has two versions of the Model Y out on the market. The first version is the one that Tesla has been selling since 2019 and that comes with the last generation of 2170 cells.
And the second version is the refreshed Model Y with 4680 cells and a structural battery pack. Tesla first started selling this new version of the Model Y at the Giga Texas opening party back in April.
The refreshed Model Y incorporates all the breakthroughs Tesla shared at the company’s Battery Day event which together were supposed to amount to a 54% improvement in range, make the vehicle lighter and improve performance and handling.
However, the Model Y AWD (Tesla’s name for the 4680 Model Y) only has a 279-mile EPA range, 5 seconds 0 to 60 time, and a starting price of $53,000.

This has caused a lot of confusion amongst the Tesla community, the subpar specs of the refreshed Model Y have even led some people to believe Tesla’s Battery Day presentation was a lie.
However, soon after the release of the Model Y AWD, Tesla sent out a letter to employees explaining why the refreshed Model Y, despite coming with the 4680 cells and a structural pack, has lower range and performance numbers than the Model Y Long Range with the last generation 2170 cells and non-structural battery pack.
According to Tesla, the main reason for lower specs is that the Model Y AWD is fitted with a smaller battery pack. This explanation, although it answers some questions regarding the specs of the refreshed Model Y, sadly raises even bigger questions.
According to the EPA, the Model Y AWD has a “fuel economy” rating of 123 MPGe (Miles Per Gallon equivalent). On its own, this number doesn’t mean much however, when we compare it to the Model Y Long Range, this is where the issues start to crop up.
The Model Y Long Range, with a 330-mile EPA range and a larger battery pack, has a fuel economy rating of 122 MPGe. This is practically equivalent to that of the refreshed Model Y which has a smaller battery pack, and a new cell and architecture that were supposed to make the weight of the vehicle even less.
Elon Musk shade light on this discrepancy at the company’s Q2 2022 earnings call.
One of the questions asked during the earnings call was “Elon noted that the 4680 plus structural pack is not yet optimized. Can you please share the general path of 4680 in structural packs in terms of cost efficiencies when compared to the traditional 2170 pack?"
And in his response Musk said “so structural pack where we get dual use of the battery cells as structure and as energy storage in the same way that an aircraft gets dual use of the wing as a fuel tank and as a wing is, I think, unequivocally, from a physics standpoint, the superior architecture. It's the A architecture. Now because it is new, we'll start off getting, I don't know, aspirationally a C within an A architecture.”
Musk and Drew Baglino, the Senior Vice President of Powertrain and Energy Engineering at Tesla, echoed similar sentiments when discussing the 4680 cells.
According to both executives, the 4680 cells hold a lot of promise however, Tesla is currently focusing on scaling production, as a result, in hopes of minimizing the number of new technologies coming at once, not all the breakthroughs announced at Tesla’s Battery Day that were meant to increase the energy density of the 4680 cells have been integrated into the batteries currently in production.
However, even though both the structural pack and 4680 cells have not yet been optimized to the fullest of their potential, one of Tesla’s competitors still believes the refreshed Model Y is a design masterpiece.
Toyota, which has been the slowest of the largest auto OEMs to begin the transition towards fully electric vehicles, recently tore down the Giga Texas Model Y and in response the Japanese automaker was positively stunned.

A Toyota executive who took part in the Model Y teardown spoke with Automotive News in conditions of anonymity and said about the all-electric crossover “taking the skin off the Model Y, it was truly a work of art. It’s unbelievable.”
Toyota estimates Tesla’s use of structural battery pack and front & rear casting has enabled the EV maker to cut 220 pounds from the weight of the Model Y. In addition, Toyota believes this approach has allowed Tesla to increase the Model Y’s range while at the same time decreasing manufacturing cost.
Overall Toyota was so impressed with the Model Y, the all-electric crossover has been a wakeup call to the Japanese automaker with one executive stating “it’s a whole different manufacturing philosophy. We need a new platform designed as a blank-sheet EV.”
Currently, it’s not exactly clear what kind of specific changes Toyota plans to make to its EV strategy following the Model Y tear-down, however, we will be sure to keep you posted once we learn more about the Japanese automaker.
