Here's how clean a Model S is in Singapore (and elsewhere)

We would like to clear up the situation concerning our customer in Singapore. The Model S that our customer imported into Singapore left our factory in 2014 with energy consumption rated at 181 Wh/km. As the Land Transport Authority has confirmed, this qualifies as the cleanest possible category of car in Singapore and entitles the owner to an incentive rather than a fine.

Model S achieves this result because CO2 emissions in gas-powered cars are far higher than in electric cars. In Singapore, electricity generation releases roughly 0.5kg CO2/kWh. Based on energy consumption in Model S of 181 Wh/km, this results in 90g CO2/km. Driving an equivalent gas-powered car like the Mercedes S-Class S 500 results in emissions of approximately 200g CO2/km. And because of oil extraction, distribution, and refining, approximately 25% more has to be added on top of that to calculate the real carbon footprint of gas-powered cars. That means an electric car like the Model S has almost three times lower CO2 per km than an equivalent gas-powered car. Moreover, as Singapore increases the percentage of grid power from solar and wind, the CO2 from electricity drops with each passing year.

We are having cooperative discussions with the LTA to ensure a proper understanding of these issues and to make sure that they are correctly testing our customer’s Model S. Based on the positive nature of those discussions, we are confident that this situation will be resolved soon.
