We all love the smell when we take delivery of a brand new car but a report last year by a US environmental group suggested that the “new car smell” was actually due to toxic chemicals. Cars that caused the most concern included the Nissan Versa, Chevrolet Aveo, and the Kia Rio. While the report did not specifically mention a direct health risk, it noted that some toxic chemicals were found to be at five or sometimes even tens time the level than would be found in an average home.

Now, a new report from the same group seems to indicate that car manufacturers have changed their manufacturing processes to reduce the toxicity of the new car smell.

The car with the best marks was the Acura RDX SH sport-utility vehicle. Three Smart cars made the list of 10 best picks, as did two Chevy models and two Toyotas. Also among the lauded models were the Chevy HHR SUV, as well as the BMW M5 and Honda Accord EXL sedans.

Among the worst vehicles, according to the rankings, were the Mitsubishi Eclipse Spider convertible and Suzuki Reno hatchback, as well as the BMW 120i and Volkswagen Beetle convertibles.

So, the next time you get into a brand new car and breathe in that oh-so-fresh new car smell you can relax and not worry that you are being slowly poisoned by your new purchase. The bad news? As soon as you pull off that lot, you’ll ask yourself if that new car smell was worth eating all that depreciation.
