It passes with flying colors.
If you want to test a modern car before production, you usually take it to the Nurburgring, an off-road course, or some region of the world where conditions are less than habitable. While all these cars are tested in hot regions like South Africa as well as cold ones like Norway and Finland, Lexus has decided that the best way to test one of its cars in icy conditions is to literally deep freeze it for 12 hours. And interestingly enough, this testing was carried out on a car that has been in production for some time and has thus already passed all relevant tests.
So why do it? Well, it shows that Lexus is so supremely confident in its build quality that it doesn't need to specially adapt a vehicle to deal with such an intense freeze. And rather than wait for the car to thaw out, Lexus went the extra mile by sending it for a test drive immediately after the car in question, a Lexus LC Convertible, had been extricated from its chilly container. Most impressively is that the freeze was carried out with the folding soft-top down, so the cabin had absolutely no insulation from the cold of Millbrook Proving Ground's industrial-scale refrigeration unit.
At 18 degrees below freezing, the conditions inside the chamber were cold enough to freeze rubber. On top of that, the car was sprayed with water before the unit was switched on so that a sheet of ice would form over the body. This is also the longest that a vehicle has spent in the icy chamber, but even with all these factors at play, a high-speed test by a professional stunt driver 12 hours after the car was stored in the freezer couldn't bring about any faults. The climate control system fired up just as quickly as the engine and quickly created a comfortable environment for the driver. With such an impressive result, it goes to show that Lexus owners aren't bluffing when they boast about their cars' reliability. Great job from Lexus.
