Don't worry, the e-tron graphic isn't on production models.

The 2016 Audi A3 e-tron plug-in hybrid, which will start at $37,900 before incentives and government tax credits, is set to arrive at US dealerships this October. The e-tron joins Audi's burgeoning A3 small car lineup, which consists of the A3 sedan, A3 Cabriolet, and S3 sport sedan.

From the front, the A3 e-tron looks quite ordinary.

A formal roofline hints at good space inside.

The A3 e-tron's interior is minimalist, with limited switchgear and clean lines.

Audi's A3 e-tron is likely to be most at home in an urban environment.

Dead-on, the e-tron is particularly hard to distinguish from other A3-family models.

Audi's four-ring logo cleverly swings aside to reveal the battery's charge port.

The turbocharged, 1.4-liter four-cylinder under hood is tidily packaged.

It's somewhat surprising to see Audi use analog gauges in this high-tech e-tron application.

The e-tron's seven-inch retractable MMI infotainment screen is optional.
