Toyota has said it may release diesel versions of its Lexus luxury range in Europe by 2006 to catch up with local rivals, according to the Detroit News. "Japanese automakers, including Toyota, have been slow in developing diesel engines while the Europeans took the lead," the newspaper cited managing director Tokuichi Uranishi, who oversees the company's European business, as saying in an interview in Japan. Diesel Lexus cars will be ready in "two to three years," he reportedly said.
