Corolla, the best-selling Toyota nameplate of all time, enters its 52nd year with minor upgrades after receiving a sportier exterior styling last year.

For 2018, all grades gain driver and front passenger illuminated visor vanity mirrors. The XLE and SE grades feature a leather-trimmed 3-spoke steering wheel with controls for audio, Multi-Information Display, Bluetooth hands-free phone, and voice command.

Part of the Corolla's ongoing success can be attributed to its wide appeal. The model line covers the gamut of tastes and needs with the L, LE, LE Eco, XLE, SE, and XSE grades. There's a sporty, sophisticated look to all thanks to Bi-LED headlamps on the L, LE, and LE Eco grades, and Multi-LED headlamps come standard on SE, XSE, and XLE grades. The sporty SE and exciting XSE roll on standard 17-inch alloy wheels.

The 2018 Corolla LE Eco is the most powerful Corolla in the line, as well, with a specially tuned 140 horsepower, 1.8-liter four-cylinder engine. A savvy combination of powertrain technology and aerodynamic features also help boost fuel economy in this model. The Corolla LE Eco cheats the wind with aerodynamic underbody covers and a color-keyed rear spoiler, which brings its coefficient of drag down to an impressive 0.28 compared to 0.29 and 0.30 in other Corolla models.

Corolla's advanced Continuously Variable Transmission with intelligence Shift also helps maximize fuel economy. It's programmed to respond more like a conventional geared automatic using discrete stepped shift points for acceleration and deceleration. The CVTi-S even mimics the familiar characteristics of hydraulic automatics by creating a sense of positive shift engagement.

All 2018 Corolla models come standard with TSS-P, a system that bundles the Pre-Collision System with Pedestrian Detection; Lane Departure Alert with Steering Assist; Dynamic Radar Cruise Control; and Automatic High Beams.
