The Model Y shares about 75% of its parts with the Model 3. This helps Tesla benefit from economies of scale, as well as get the Model Y to market faster.
From the looks of it, the whole front section of the Model Y looks the same as the 3 – the headlights, hood, and likely all the internals and suspension are the same. Inside the Model Y, the same 15.0 inch screen and dash appear in both Tesla electric vehicles.
Dimensions of both vehicles are very similar. The Tesla Model Y is 3 inches longer, almost 2 inches wider, and then of course substantially taller (7 inches) taking it into crossover vehicle territory (up from the Model 3 sedan class).
The long range dual motor Performance Model 3 weighs in at 4,072 lbs, while the Model Y long range dual motor is 400 pounds heavier at 4,416 lbs curb weight.
Ways the Model Y and Model 3 are different
The Model Y has a much taller roofline, which gives the interior a more spacious feel, and allows a third row seat option. Interior trunk space is 66 cubic feet, while the smaller Model 3 only has 15 cubic feet.
Being bigger, heavier, and less aerodynamic than the Model 3, the Model Y is slower, and has less range. With 315 miles of range and a 0-60 mph time of 4.8 seconds, the all-wheel-drive Model 3 has a range of 322 miles and a 0-60 mph time of 4.4. seconds.
The Model Y is only available in all-wheel drive (dual motor), while the Model 3 is available in rear wheel drive and all wheel drive configurations.
Model Y and Model 3 Size Difference
The Tesla Model Y is 187 inches long and the Tesla Model 3 is slightly shorter at only 184.8 inches long. As for width, the Model Y is 2.8 inches wider. The big difference is in height – the crossover Model Y is 63.9 inches tall overall, while the Model 3 sedan is 56.8 inches tall.
The larger exterior dimensions of the Model Y translate into more passenger space when compared with the Tesla Model 3.
For the driver and front seat passenger, the Model Y has one more inch of headroom and 1 inch less of leg room than the Model 3. For rear seat passengers, it gets even better – there is 2 inches of additional head room, and 5.3 inches more legroom. For some reason, there is 2 inches less hiproom in the rear seat of the Model Y than there is in the Model 3 – perhaps because of additional reinforcement and design for the taller hatchback design, or even the positioning of the optional 3rd row seat.
Weight comparison of the Tesla Model 3 and Tesla Model Y
The Model Y is a heavier vehicle – with a curbweight of 2003kg, while the same long range dual motor version of the Model 3 weighs only 1860kg – 143kg less. The extra curbweight causes a slight reduction in the available weight for passengers and cargo. The Model 3 is rated for 418 kg, while the Model Y can take 402 kg of passengers and cargo.
