Lexus would like to remind drivers who frequent the city of London that the GS450h is a credible sports sedan which falls well below the maximum penalty which will be in effect as part of the upcoming Congestion Charge. Emitting 185g/km of CO₂ will allow for a daily charge of £8, as compared to the £25 maximum penalty which many performance and luxury vehicles will be subject to.

We're not going to dispute the facts as presented by Lexus, but we'll also stop well short of suggesting that the GS 450h is the eco-friendly choice (there are certainly other options). Still, its comparatively low emissions, along with its 35.8mpg in the combined cycle, give a possible reason to choose it over some of its rivals, if for none other than to save some extra cash.

After the break, Lexus provides a chart comparing the power, acceleration, CO₂ emissions, combined fuel economy and congestion charges of the BMW 540i, Jaguar XF and Audi A6 4.2 V8 FSI against its own GS450h. Very thoughtful of them, wouldn't you say?
