Powertrains are a 2.0L I4 with a five-speed, front-wheel drive manual transmission or optional four-speed automatic transmission with "sport shift" manual shifting capability or a 2.7L V6 available with the automatic only. Four wheel drive is optional with a Borg-Warner torque controller system. In some markets, the Tucson is also available with a 2.0L diesel engine equipped with common rail technology. The earlier diesels had 113bhp (84kW; 115PS), and the later ones 140bhp (104kW; 142PS) and a 6 speed manual gearbox. These later models are capable of returning over 45 mpg with almost the same performance as the 2.7L petrol engined models.
In the United States, the Tucson is offered in base GLS, mid-line SE, and top-tier Limited (formerly LX) trim levels for 2007 models. Earlier 2005 and 2006 models were offered as GL/GLS/Limited. Standard equipment includes air conditioning, cruise control, six airbags, electronic stability control, a CD player, alloy wheels, remote keyless entry, and premium cloth seats. The SE adds to the roster with contrasting gray body cladding, a different alloy design, an AM/FM/Cassette/CD as well as fog lights and a front windshield wiper de-icing grid. The Limited adds leather seating surfaces, a 6-disc in dash CD changer, body-colored cladding, automatic climate control, and heated seats. The SE and Limited are only available with the 2.7-liter V6. The GLS comes only with the 2.0-liter four cylinder.
