Toyota on Thursday unveiled its all-new 11th-generation Corolla, the latest iteration of its ubiquitous economical compact.

The 2014 Corolla gains about 4 inches in wheelbase, less than an inch in width and has a more-tapered aspect, with the front and rear sections stretched for a more elegant sweep of line and a more aerodynamic shape. LED low-beam headlights are standard on all models.

More high-strength steel should improve handling and safety performance by creating a stiffer structure, and additional sound-proofing materials in the cowl, dash and fenders will make it easier to hear the Bluetooth Entune sound system.

A new Continuously Variable Transmission (CVTi-S in Toyota-speak), adds a note of fresh technology to the design. The CVTi-S is a cornerstone of a new-for-2014 LE Eco model, which also features a new 1.8-liter, 140-horsepower engine with Valvematic, a technology that more closely controls intake valve lift and timing. Non-CVTi-S models will offer a choice between a 6-speed manual transmission or the current, conventional 4-speed automatic.
