It was -15°F this morning on my drive in. It was a little tough getting started even though I left the heater plugged in all night. Belched really thick black smoke for the first minute. But once the benz got warmed up it seemed to have more than the normal # of horses. Could be imagined or it could be due to denser air entering the turbo.

When it gets really cold the shocks get real stiff and the tires lose pressure resulting in lots more road sounds.
