Geely's Volvo Car Group expects the Chinese roll-out of its new XC90 and, next year, the S90, to drive sales through a slowdown in demand in the world's biggest auto market, its top executive said. Chief Executive Hakan Samuelsson said Volvo would not join in any price war to prop up volumes as the company tries to make inroads into a high-end car market dominated by German rivals, although some analysts said he may be tempted to cut prices.
