LIVE: US auto sales

Automakers will release their sales data for September throughout Monday.

Economists forecast that total vehicle sales rose at a seasonally adjusted annual rate of 17.45 million, according to Bloomberg.

Ford spooked the industry last month when it suggested that the auto market has peaked after a record year of sales in 2015. The company said during its sales call with analysts that it would be "really tough" to match the performance of last year.

Those comments were accompanied by other concerns about carmakers spending more on the incentives that attract prospective buyers. This usually happens when the market has peaked and companies are trying to guard their market share from competitors.

However, the mix of spending on incentives reveals that higher spending may not be all that hurtful to carmakers' bottomlines, as Business Insider's Matthew DeBord noted in his preview.

Car companies are selling lots of trucks and SUVs, which are more expensive than sedans. That makes the discounting relative, since offering incentives on an expensive SUV is less desperate than discounting cheaper cars.

Tesla on Sunday said it delivered 24,500 vehicles in the third quarter, indicating that the company is running slightly below pace for the 50,000 second-half number it set for itself. The electric-car maker releases its numbers on its own calendar that's separate from the traditional carmakers.
