Engine or motorsTwo motors: 300 kW (408 hp) xDrive45, 400 kW (544 hp) xDrive60, 485 kW (659 hp) M70 xDrive; bhp converted from BMW's kW figuresLiquid-cooled AC induction motors at the front and rear, as specified in Tesla’s original European owner guide. The guide’s separate motor maximum ratings are not added together as combined output. Exact EV Database European listings give 245 kW (60D/75D), 311 kW (90D/100D), 345 kW (P90D) and 397 kW (P90D Ludicrous), converted to bhp. P100D power is omitted because that database marks 500 kW as estimated.
Torque700 Nm (xDrive45), 765 Nm (xDrive60), 1,015 Nm (M70)–
GearboxSingle-speed automaticSingle-speed fixed gear. Tesla’s guide gives final-drive ratios of 9.325:1 for the smaller motor and 9.734:1 for the larger Performance rear motor.

Range detailWLTP 321–374 miles (xDrive45, depending on trim), 370–426 miles (xDrive60), 321–365 miles (M70)These pre-Raven versions have NEDC or EPA ratings, rather than WLTP. EV Database’s European NEDC figures include 259 miles (75D), 304 miles (90D), 351 miles (100D) and 337 miles (P100D). They are not entered in the WLTP fields. The 2019 Standard Range, Long Range and later Performance versions belong to the separate Raven generation.
ChargingBattery capacity 94.8 kWh (xDrive45), 109.1 kWh (xDrive60) or 108.9 kWh (M70) as BMW UK lists it; DC up to 175 or 195 kW, 10–80% in 34–35 minutes; AC 11 kW or 22 kWExact EV Database European listings: up to 120 kW DC for 60D/75D/90D/P90D and P90D Ludicrous, or 145 kW for 100D/P100D. AC ratings are 11 kW for 60D/90D/P90D/P90D Ludicrous, and 16.5 kW for the listed 75D/100D/P100D versions. These equipment-dependent ratings are not one universal original specification. The 60D used a software-limited 75 kWh pack (EV Database). Battery badge capacities are nominal, and estimated usable values are omitted.

Boot500 litres, 1,750 litres with the rear seats foldedTesla’s European guide specifies maximum rear cargo space behind the front seats: 2,299.5 litres (five seats), 2,002 litres (six seats) or 2,166 litres (seven seats), with the second row forward and/or folded as applicable. A separate 187-litre front boot is listed. The 357-litre area behind the third row is included in those rear totals. Maximum folded/forward figures are not entered as all-seats-up boot capacity. Early six-seat individual middle-row chairs slide and tilt but do not fold flat, as tested by Car and Driver.
Towing2,500 kg brakedUp to 2,250 kg when equipped with the towing package and within gross-weight limits, per the European guide. Its specified 19-inch winter tyres are required if towing on that wheel size; passenger and luggage loads can reduce available capacity.
Size4,965 mm long, 1,970 mm wide (2,230 mm with mirrors), 1,695 mm high; 3,000 mm wheelbase; EC unladen weight including a 75 kg driver is 2,525 kg (xDrive45), 2,580 kg (xDrive60), 2,655 kg (M70)Original European owner guide: 5,036 mm long, 1,999 mm wide without mirrors, 2,072 mm with mirrors folded or 2,271 mm with mirrors extended; 1,684 mm high and 2,965 mm wheelbase. Main 2,352 kg kerb weight is the guide’s lightest 60D/75D rating with fluids, without occupants or cargo; 90D is 2,389 kg, P90D 2,439 kg, 100D 2,459 kg and P100D 2,487 kg, varying with equipment.
Release and generation details–Tesla’s October 2015 delivery report confirms the first customer handovers in Q3 2015; contemporaneous Fortune coverage places those handovers on 29 September. Main date retains September precision. European battery/motor versions followed later; EV Database’s October 2016 or January 2017 order dates are not treated as this family’s first delivery. Six- and seven-seat layouts are options alongside the five-seat version. The 2019 Raven generation changes the front motor and damping and is documented separately.
