BMW made a strong comeback, posting 20% sales growth in the first nine months of this year, on the back of its sub-2 litre diesel engine portfolio, enabling growth faster than the market. The diesel engines have proven to be of the utmost quality, and will be made available across eight different models. Frank Schloeder, acting president of the BMW Group India said there was a reason why the company has slowed down the business as it was not sustainable and the company had to take some important decision to bring the business back on track.
