BYD, the Chinese car maker backed by US billionaire Warren Buffett, saw sales fall 11% in April compared to the same month last year to 40,100 cars although this was slightly ahead of March’s 40,027 units.

BYD, which makes batteries and some of the cheapest cars in China, did not provide comparisons with last year but, according to analysts’ data, the company sold 45,110 vehicles in April 2010.

Analysts said BYD had seen sales fall since August, largely as a result of over-expansion and an aggressive sales strategy, but seem to have stabilised at around 40,000 units.

The Chinese government’s decision to scrap tax incentives on small cars at the beginning of this year also impacted BYD’s sales in what is now the world’s largest auto market – although growth is expected to slow this year.
