The advantage of a smallish battery is that you can charge it quickly -- up to 80 percent in 30 minutes. An 11 kW Wallbox charger, installed at home, will juice up the E-Tense model in just five hours, so it will be a handy city runabout, but less useful on longer trips.

The Crossback features a Drive Assist function that can keep you in your lane, brake automatically in emergencies, and self-park. There's also keyless entry, and full digital option, with a 10.3-inch entertainment HD touchscreen with smartphone mirroring and connected navigation. The DS 3 Crossback E-Tense will come to Europe in mid-2019, but no price has been revealed yet.
