Tesla Roadster Specifications Motor
Type: 3-phase, 4-pole electric motor Max net power: 248 hp (185 kW) Max rpm: 13,500 Efficiency: 90% average, 80% at peak power Battery System Type: lithium ion. Cells: Size 18650, 3.6V, 2.2Ah (nominal). Arrangement: 6831 cells, size 18650, in 11 sheets. Each sheet contains 69 parallel strings and provides 32.4V (nominal). Each string contains 9 cells in series. 10 of the sheets provide traction power, the 11th layer provides accessory power.[17] Weight: about 990 lb (450 kg) Full-charge time: 3½ hours Estimated life: 100,000+ mi[9] Capacity: about 56 kWh[18] Performance Acceleration time, 0-60 mph (0-100 km/h): approximately 4 s Top speed: 130 mph (210 km/h) Range: 200+ miles (322+ km) on the EPA highway cycle
On the EPA highway cycle, the Roadster's efficiency is "135 mpg equivalent, per the conversion rate used by the EPA" which converts to 133 Wh/km (4.66 mi/kWh) battery-to-wheel or 155 Wh/km (4.00 mi/kWh) station-to-wheel.
Tesla also reported the battery-to-wheel efficiency as 110 Wh/km (5.65 mi/kWh) on an unspecified driving cycle (either a constant 60 mph (96 km/h) or SAE J1634 test[19]) and states a charging efficiency of 86%. This results in an overall station-to-wheel efficiency of 128 Wh/km (4.85 mi/kWh).[20]
The Roadster's engine efficiency is 90% on average and 80% at peak power.[21] For comparison, an internal combustion engine produces 6000 to 9000 Wh of output energy from each gallon of gasoline input[citation needed]. The state of tune and seasonal variations in gasoline formulation account for the output range. Transmission Type: Two-speed sequential manual |
