Net sales during the quarter went up 9.4% at R12,566.6 crore, but Q4 volumes fell almost 5% to 3.43 lakh units with demand for popular petrol models like the Alto and WagonR slowing down. The Q4 results do not include the merger of Suzuki Powertrain India, maker of diesel engines, with Maruti Suzuki. The merger has become effective on April 1, 2012, but the formalities were recently completed in March after court approvals. Maruti also merged seven insurance-related arms into itself, giving it additional cash of R200 crore.
