Redesigned for 2001, the larger of Hyundai's two front-drive subcompact cars grew slightly and gained a fresh look, but retained its previous powertrains. Front side airbags became standard. No more wagons were produced, and the base sedan disappeared, leaving only a GLS sedan. The Elantra's wheelbase grew by 2.3 inches, overall length by 3.1 inches, and height by 1.2 inches. Curb weight and interior dimensions changed little, though head and leg room shrunk slightly in the rear and increased a bit up front. A 2.0-liter four-cylinder engine remained the only possibility, though it got new engine mounts. A revised exhaust system promised reductions in noise, vibration, and harshness. Elantras could have a manual gearbox or a four-speed automatic transmission. Wheel diameters grew an inch, to 15. Shock absorbers were upgraded from hydraulic to gas-filled. Antilocking all-disc brakes were now a standalone option, but the regular non-ABS system stuck with rear drum brakes. Standard features included air conditioning, power windows/locks/mirrors, a cassette stereo, tachometer, tilt steering wheel, manual six-way driver's seat, front-seat lumbar adjustment, intermittent wipers, and a split-folding rear seat. Child-seat anchors were installed, and front seatbelt pretensioners had force limiters. Options included cruise control, a 100-watt CD stereo, and a sunroof. Competitors included the Dodge/Plymouth Neon, Ford Focus, Honda Civic, Mazda Protege, and Nissan Sentra. A GT four-door hatchback joined the sedan during the 2001 model year. Hyundai's warranty was one of the industry's longest: 5 years/60,000 mile basic, 10/100,000 powertrain.
