Toyota Motor Corp. unveiled the remodeled Celsior luxury sedan Thursday as part of its efforts to compete with quality European automobiles.

Toyota President Fujio Cho said the Celsior -- with an engine displacement of 4,300cc -- will be launched abroad in October as the Lexus LS430.

The company said the car has expanded cabin and luggage space, smooth acceleration and environmental technology that reduces emissions of harmful gases by 75 percent from the levels permitted under Japan's 2000 exhaust emission regulation, which takes effect in October.
