Tesla responds to Singapore’s Model S CO2 emissions test, and could it be as simple as poor math?
Last weekend we reported on Singapore’s Land Transport Authority (LTA) slapping an important tax surcharge on the Tesla Model S after running some emission tests and rating its energy consumption at 444 Wh/km. After accounting for Singapore’s grid emission factor of 0.5 g CO2/Wh , the LTA determined that the Model S somehow ended up on the worst end of the global city’s scale for vehicle pollution (C3 band).
Tesla has now issued a response (you can read the full statement below) and claims that when the Model S tested by LTA left Tesla’s factory in 2014 (yes it took a while to import it), it had an energy consumption rated at 181 Wh/km, less than half of what Singapore’s transport agency is claiming. How can we account for the discrepancy?
