With any internal combustion engine the main components to make it run are fuel and air. When an engine is cold (internal temp) there needs to be a different mixture of fuel and air to make it run. That's why older cars with engines with carburetors (the components that mixes air and fuel) you needed to let the engine "warm up" before driving. The air (ambient or outside temperature) must be within a range to optimize the combustion. On newer engines that use "Electronic Fuel Injection" (EFI) the air and fuel ratio are controlled by sensors. One of those sensors is a cold start sensor that sits right under the air intake hose on a 960. The sensor is sensitive to a range of ambient air temperatures and if the ambient temperature falls under that range i.e. it's damn near freezing!, the car will be harder to start. That is in addition to the internal cold temp of the engine metal.
