Tesla Model X 90D gets 257-mile EPA range

The P90D performance model brings a slight range penalty.

Due to be unveiled later tonight, the Tesla Model X has received an official range rating from the Environmental Protection Agency.

The 90D variant, equipped with a 90-kWh battery pack, offers the best range of 257 miles and a combined city/highway rating of 92MPGe, consuming 37 kWh per 100 miles.

The performance-focused Model X P90D brings higher performance but with a slight range penalty, bringing the EPA-certified driving distance down to 250 miles on a full charge.

The numbers are fairly close to the Model S 85D and P85D, which offer respective ranges of 270 miles and 253 miles despite less energy capacity. Interestingly, the range discrepancy between the standard dual-motor and performance models is 17 miles for the Model S and just seven miles for the Model X.

The EPA website does not list information for the additional Model X variants, which are not expected to arrive until next year. First deliveries will be limited to the $132,000 Signature Series range topper, to be followed by less luxurious trims and smaller battery packs.

Tesla has already outlined many of the Model X's features, however there could be a few surprises at the launch event.
