The Model Y L “Long Wheelbase” Premium is the largest and most expensive version of Tesla’s best-selling vehicle. There’s a lot to stack up and compare.

All Tesla Launch Series carry a premium. In this case, the standout feature of course is the added 7 inches in length and a third row.

The Model Y L seats six adults across three rows, with captain’s chairs in the second row — which no other Model Y offers. The added length means more rear cabin space, though how tolerable that third row is for adults on longer trips remains to be seen.

Suspension: The suspension is different from any other trim. The base Model Y uses passive shock absorbers and the Premium gets frequency-dependent passive dampers. The L runs electronic continuously variable shock absorbers that adjust in real time. For a three-row vehicle regularly carrying a full load, that's a practical difference.

Extras: The tech loadout is the strongest in the lineup. The L gets 18 speakers, seven USB-C ports, an 8-inch rear touchscreen, FM radio, and 19-inch Machina 2.0 wheels — all standard. All six exterior colors are included at no extra charge, and a tow hitch comes standard. Tesla also bundles in 12 months of Full Self-Driving (Supervised) and 12 months of Premium Connectivity. After that, FSD runs $99 a month and Premium Connectivity $9.99 a month.

Range: Range comes in at 325 miles estimated. The EPA hasn’t issued a final rating yet, so that number could move. But whatever the EPA number is, 325 miles-ish is not an outstanding feature for the price, so keep that in mind.

Minivan competition? The Model Y L is aimed at the three-row SUV and minivan segment, where buyers prioritize passenger capacity. But that segment is price-sensitive and ICE (internal combustion engine) competition is both stiff. Some (many?) buyers may elect to wait for the standard Model Y L — whenever it arrives. That should be more affordable and configurable. (So, Is Tesla coming out with a traditional minivan like the Chrysler Pacifica or Honda Odyssey? AI thinks not.)
