New for 2007, the Elantra sedan is wider and longer, with more interior room than ever, enough to push it close to the mid-size category, as far as government/EPA classifications go. With 97.9 cubic feet of passenger room and 14.2 cubic feet of trunk space, it has the most interior volume (passenger volume plus trunk space) for a sedan in its class. The Elantra’s total interior volume of 112.1 cubic feet even surpasses the interior volume of the near-luxury Acura TL (110.4 cubic feet) sedan. The Elantra’s 14.2 cubic foot trunk capacity also beats Civic and Corolla. The '07 Elantra's standard 2.0-liter engine develops 138 horsepower and qualifies for SULEV (Super Low Emissions Vehicle) status. A five-speed manual transmission is standard in the Elantra, with a four-speed automatic available optionally. Three trim levels are offered: GLS, SE and Limited. All versions come standard with power windows, power heated rearview mirrors, power door locks, remote keyless entry with alarm and trunk open, rear center armrest with cupholders, intermittent windshield wipers and tilt steering wheel. Front-seat side-impact airbags, full-row curtain airbags, anti-lock brakes with Electronic Brakeforce Distribution and active front head restraints are also included. SE versions get all the equipment in the GLS Preferred Package plus a telescoping leather steering wheel with secondary audio controls, leather shift knob, 16-inch alloy wheels with P205/55HR16 tires and trip computer. At the top is the Limited, which takes the Elantra upscale by building on the SE equipment with leather seating surfaces, leather door panel inserts, leather armrest and heated front seats. A Sun and Sound package is available that combines a power sunroof and a 220-watt premium audio system featuring AM/FM/6-CD changer/MP3 with auxiliary input jack and an external amplifier.
