However, the Model Y L offsets its larger footprint using a slightly expanded battery pack alongside dedicated aerodynamic tweaks, including an integrated rear spoiler molded directly into the body shell.AdvertisementAdvertisementThe EPA data reveals a significant difference in wheel-size range degradation between the standard and long-wheelbase variants:Standard Model Y Premium AWD: Rated at 327 miles on standard 19-inch wheels, range drops by 24 miles down to 303 miles when stepping up to 20-inch wheels.Long-Wheelbase Model Y L Premium AWD: Rated at 332 miles on 19-inch wheels, range drops by just 4 miles down to 328 miles on 20-inch wheels-a minor drop of roughly 1.2 percent.The minimal 4-mile penalty allows Model Y L buyers to select the larger 20-inch wheels without sacrificing meaningful driving range on daily commutes or highway road trips.The Model Y L Premium AWD carries a base price of $61,990 ($63,630 including mandatory destination and order fees).
