In the brushed alloy threshold plates under all the doors. In the tight seams between every piece of trim. You feel it in the beautifully rendered articulating hinges for the center-console-bin lid. And as we've noted before, its interior trimmings and attention to detail trump almost any other car's on the market. Its ride quality has not a hint of harshness (assuming you leave the three-way-adjustable shocks out of sport mode). Its transmission shifts are utterly without tactile or aural shock. #04 CADILLAC SRX DRIVER#Every test driver determined the VW luxury liner to be the finest choice for a long interstate haul. Still, we hardly consider the Touareg the loser. LOWS: Inattentive throttle, feather-light and uncertain steering, reluctant handler. HIGHS: Faultless interior execution, rock-solid structure, great-sounding stereo. Also, although the Touareg might carry the second-lowest as-tested price at $53,265, that's still $6765 more than what VW led us to believe the last time around. And with a hefty 5412-pound curb weight, the Touareg had the worst weight-to-power ratio of this group (17.5 pounds for each VW horse to pull, compared with 14.3 for the Infiniti). In this test of utes, which is more focused on performance, the VW's Audi-sourced V-8 was the weakling. #04 CADILLAC SRX ZIP#Besides, it's our magazine, not yours, so zip it. You might ask why sixes were mixed with eights, but that's the way the pricing came out. Half the vehicles in the previous comparo were powered by six-cylinder engines, which made the VW's 310-hp V-8 seem like a nitro-burning dragster. None of the competitors assembled here was available for last January's eight-truck flog. 'Reg-N-Effect: 2015 Volkswagen Touareg Tested! Besides, off-roading is so uncomfortable. Also, both came with high-performance street tires with shallow tread that would have hobbled even a Hummer, off-road, anyway. These add cost and weight (you can order either vehicle without the air suspension), which is unfortunate for the Germans. The Porsche and the VW, which were designed together and share many parts, do have low-range gearing (just like a Jeep CJ7!) and air bladders that will raise their bodies until they look really silly. We would not go off-road, though, because, well, why would we? Sure, all these vehicles have all-wheel drive, but even the kid at an Athens plant store recognized them as "a buncha fancy wagons." The Cadillac and the Infiniti are based on sports sedans (the CTS and the G35, respectively), not pickup trucks. #04 CADILLAC SRX FULL#We would crank the air-conditioning units to full chill, play with the navigation systems, adjust our power seats, raise power-adjustable suspensions for no reason at all, and still sprint to 60 mph in an average of seven seconds just because we could. But, you know, screw that! It's our power, after all, and we're going to use all of it as often as we want. Until we ran out of gas, which, in a group that averages 15 mpg, wouldn't take long. With the equivalent of 954 kilowatts of electric power pumping from these pumped-up utes, we could have powered a sizable neighborhood. If the AC evaporator is fully busted, then say goodbye to any level of cold air.All told, we had 1280 horsepower split fairly evenly among the four V-8 engines that power the Cadillac SRX (320 hp), the Infiniti FX45 (315), the Porsche Cayenne S (335), and the Volkswagen Touareg (310). If it’s just starting to go, you might still get some cold air, it will just be like a brisk spring day amount of cold, rather than dead of winter cold. The temperature of the air depends on how broken the AC evaporator is. Unless it’s a frigid day, and you turn on your fans, you simply won’t have a way of getting cold air into your cabin. If your AC evaporator is busted, your air conditioning system doesn’t really have a way of producing cold air. But, hey, you just never know what could go wrong. And because the evaporator is a heat exchanger, it absorbs the heat, keeping you cool.Īnd that’s how you keep from leaving sweat marks all over your nice car seats.Įvaporators are extremely durable, and you usually won’t ever have to replace yours. At the same time, the blower motor is pushing warm air across the evaporator. Inside the evaporator, the refrigerant is transformed into a gas (hence the name evaporator). Liquid refrigerant is metered into the evaporator core by an expansion valve or orifice tube. So, how’s it work? Well, I won’t bother you with all the ins and outs, because, frankly, I don’t think you really care that much. That seems like it might be an important thing, yeah? How important is the AC evaporator core? Well, it’s the part of the air conditioning system that’s responsible for, you know, making the air cold. With that out of the way, let’s get to the evaporator core, which is a really big part of your air conditioning system.
