In late 2010 and early 2011, Lexus began sales of the CT 200h, a compact four-door hybrid hatchback designed for Europe, in multiple markets. Sales of lower-displacement regional models were also expanded, beginning with the ES 240 in China followed by the RX 270; Japan, Russia, and Taiwan were among markets which received model variants intended for reduced emissions or import taxes. In March 2011, the Tōhoku earthquake and tsunami caused severe disruption to Lexus' Japan-based production lines, hindering the marque's near-term sales prospects. Lexus' U.S. executives stated that due to vehicle shortages amidst close competition from BMW, Mercedes-Benz, and Audi, the marque would not remain the country's top-selling premium car brand.
