Sorry to derail this thread by going off subject but Model Y price just got lowered in Canada to $69,900. If it was selling like hotcakes I doubt Tesla would lower the price now? Sorry for the interruption, let’s go back to Mustangs, beer, pies and bikes.

From the article... Did you write it SE?"They go back to Lexus because they’re familiar with Lexus. They have a notion in their heads about Lexus being a great brand that they acquired years ago, without the taste of Tesla to put it in context. Now, as for anyone who goes and test drives a Tesla Model Y and a Lexus RX and chooses a Lexus RX — that person, if they exist, baffles me."ROFL.
“It’s like it took all the good things about the Model 3, it kept them…but it took some of the bad things…and made them better… It’s an improved Model 3, if you think about it that way.”
08.06.01 Electric cabin heaterThe heater unit incorporating a variable speed electric fan is located in the front of the chassis tub with ducting directing the blown air to defrosting, face level and floor level vents in the passenger compartment.The heater element is of the heat pump, drawing HV electrical energy from the battery pack High Voltage.Tesla Model Y’s heat pump reduces the energy required by the HVAC system in both heating and cooling scenarios. The energy required to heat the cabin varies by weather and occupant comfort needs, but on-average consumes approximately 10% of the total energy available for driving. However, even moderately cold weather (0°C), consumption can increase to 25% or more. A heat pump consumes a small amount of electrical energy to thermodynamically “upgrade” low-temperature (less useful) thermal energy to higher-temperature (more useful) thermal energy, making it suitable for occupant comfort. That is, for a given electrical power input, a heat pump will return 1 to 5x in useful heating power; an electrical cabin heater provides 1:1 in heating power, and therefore is far less efficient.Typically, this is accomplished using conventional refrigeration system components, e.g., compressors, valves, heat exchangers and so on, configured or connected together in a specific way. Tesla’s heat pump uses conventional components with unconventional flexibility or cycle configuration. A heat pump must generally have a low-temperature source from which to draw energy. Tesla’s system enables the heat pump source to be either the power-train coolant loop, e.g., low-temperature waste heat produced naturally by the vehicle while driving, ambient air, the battery thermal mass, the cabin thermal mass, or combinations thereof. Another advantage of this architecture is the ability to reject heat into the battery pack via a liquid-cooled condenser for a limited amount of time during cabin cooling scenarios when the temperature of the battery is modest. Therefore, for most startups with AC on, the relatively cool, well- coupled, large thermal mass serves to lower discharge pressure and therefore reduces compressor input power relative to a conventional air-cooled condenser setup.Modern automotive heat pump systems using an HFC/HFO refrigerant suffer from low heating capacity in extremely cold ambient conditions, e.g., minus 10°C and below. Therefore, these conventional systems retain an expensive high-voltage cabin heater to cover heating deficits whenever the heat pump capacity is insufficient. Tesla’s heat pump system also provides ways to remove a cabin air high voltage PTC heater completely by using the compressor as an electrical heater in specific scenarios. In fact, the electrical power draw capability of the compressor significantly exceeds a typical HV cabin PTC heater capability. This last point is accomplished via Tesla’s unique architecture – the cycle is configured in such a way to provide a controlled environment for the compressor, regardless of ambient conditions, and ultimately unlocks the full electrical input power. Therefore, Tesla’s thermal system can sometimes operate like a heat pump (heat efficiently) and sometimes like an electrical heater when heat pump capacity is not sufficient for comfort – using the same compressor.
The problem with heat pumps is that the coils freeze over

You need to look at Mitusbishi Hyper Heat or Samsung Max Heat splits.

How will Tesla rivals top this?Model Y crossover teardown shows just how high the bar has been set for EV innovation
Other EVs use heat pumps, but Munro saidthe introduction of the Octovalve makes theModel Y’s heating, ventilation and air-conditioning system different from anything he’sever seen in a car and looks more like something from the aerospace industry.
“It’s going to be a long, long time,” Munrosaid, “before somebody catches up to it.”

We use them here at work to hold steel blocks many times the weight of a Tesla battery pack!WTF??

Best car I ever owned: hold my three kids, my dog and all their sh*t. Rips when you hit the right pedal, stops very hard, corners...ok and looks decent. This car is a deal for $60k and will be unstoppable below that.
Completely agree, particularly when the car is properly assembled.
Ha! The Tesla shorts would see it try to buy up all the corner molding.
