The performance ambitions of electrified city driving are embraced in the updated BMW i3 and i3s. Though the drive system remains unchanged, the new i3s boasts 184hp compared to the standard model’s 170hp, though both still drive the rear wheels. Range is pegged at 124 miles on both models, though an optional range extender takes the figure past 200 miles. The i3s also gets sportier body trim, wider wheels, and a wider track, and the new ESC system supposedly allows controlled drifts. Available safety features include park assistant, traffic jam assistant, and collision warning with city braking.
