Comparison, Exhaust and Vermont

The most significant compositional difference between the exhaust PM from combustion of the 2 fuels was the ratio of polar to non-polar species: 46% assigned polar for B0 vs 68% polar compounds for the B20 fuel. We are unaware of previous studies reporting this type of comparison of the exhaust PM.

We compare real-world tailpipe emissions data for one HEV to the same manufacturer and model year CV counterpart to quantify the CO 2 emissions and fuel consumption benefits of the HEV during real-world driving across all northern Vermont seasons on terrain that includes steep and rolling hills.

With lower exhaust heat, heat efficiency was enhanced, and consequently, fuel efficiency was enhanced as well. An Eco Savings Record screen, new to both the 2012 updated Prius and the Prius Plug-in, allows drivers to measure their savings over a customizable pre-set comparison vehicle. Vehicle deliveries begin in Spring 2012.
