CAFE Case Study: Lexus NX Gets Different Fascia To Qualify As "Light Truck"
Although we’ve covered CAFE and its effects on the new car market before, the launch of the Lexus NX provides us with an interesting example of just how far auto makers will go to have their offerings classified as “light trucks” under the U.S. regulatory scheme which incentivizes manufacturers to offer these sorts of vehicles beyond mere market forces.
To recap quickly, CAFE splits vehicles with a gross vehicle weight rating (GWVR) under 8,500 lbs into two categories: cars and light trucks. Each vehicle has a “footprint” formula based on the vehicle size, with fuel economy targets it must meet. These are added up to a “fleet average” for each manufacturer, and there are a whole host of byzantine rules regarding “credits” for different technologies, like start-stop systems, hybrids and EVs that can be applied. They key concept here is that two vehicles can be the same “footprint”, but the “light truck” has to meet a fuel economy standard that is less stringent than the “car” standard. This ( along with market forces) has been one reason why crossovers have become such a prominent segment in the American auto market.
As the crew at Top Gear Philippines discovered, the Lexus NX doesn’t just meet the standard of being a “light truck” by virtue of its approach angle. The solution is a different fascia for North American markets, such as the one shown above. Compare that to the one below, which has a “fuller”, square-jawed appearance.
The change in fascia isn’t the most onerous hurdle to overcome, but it does illustrate the fickle nature of the regulations, and how far auto makers will go to meet them – and exploit the various loopholes contained within.

- Daniel J Until we get a significant charging infrastructure and change times get under 10 minutes, yes
- Mike I own 2 gm 6.2 vehicles. They are great. I do buy alot of gas. However, I would not want the same vehicles if they were v6's. Jusy my opinion. I believe that manufacturers need to offer engine options for the customer. The market will speak on what the consumer wants.For example, I dont see the issue with offering a silverado with 4cyl , 6 cyl, 5.3 v8, 6.2 v8, diesel options. The manufacturer will charge accordingly.
- Mike What percentage of people who buy plug in hybrids stop charging them daily after a few months? Also, what portion of the phev sales are due to the fact that the incentives made them a cheaper lease than the gas only model? (Im thinking of the wrangler 4xe). I wish there was a way to dig into the numbers deeper.
- CEastwood If it wasn't for the senior property tax freeze in NJ I might complain about this raising my property taxes since most of that tax goes to the schools . I'm not totally against EVs , but since I don't drive huge miles and like to maintain my own vehicles they are not practical especially since I keep a new vehicle long term and nobody has of yet run into the cost of replacing the battery on an EV .
- Aquaticko Problem with PHEV is that, like EVs, they still require a behavioral change over ICE/HEV cars to be worth their expense and abate emissions (whichever is your goal). Studies in the past have shown that a lot of PHEV drivers don't regularly plug-in, meaning they're just less-efficient HEVs.I'm left to wonder how big a battery a regular HEV could have without needing to be a PHEV.
