This here is a quick test drive review of the second generation Nissan LEAF in Canada, presented by Toronto Electric Vehicle Association TEVA in winter conditions of -7°C (19.4 Fahrenheit).
During the highway test drive with heated seats at 20°C (68 Fahrenheit), battery capacity decreased from 93% (estimated 183 km) to 83% (164 km estimated). In other words, 10% was worth some 19 km (12 miles) and the total range at 100% would've been 190 km (120 miles).
The energy consumption was calculated at 29.3 kWh/100 km (62 miles), but again, the low temperature and the route's impact was rather big. In the summer, there shouldn't be any problems hitting the 151 miles of EPA range.
From other insights, e-Pedal (single pedal driving without creeping) works great, regen is strong, and ProPilot assist does the job.
