2013 Prius vs 2013 Camry Hybrid - Battery Size and Curb Weight

Ford used a 330V battery while Toyota used a lower voltage and a boost converter. Cobb, you know better than most what a difference extra capacity makes. For all of the advantages of Toyota's system, they can be eliminated with a bigger battery. It's that simple.
Actually, Toyota did not forget to bump the battery size on the 2013 Camry Hybrid, which has a 1.6 Kwh battery, compared to the Prius's 1.3 Kwh battery. This represents a 23% increase in battery size. The 2013 Camry Hybrid weighs about 3,500 lbs, compared to the 2013 Prius's weight of 3,040 lbs. The difference in weight (15%) is actually less than the 23% increase in battery size. So, in fact, Toyota overcompensated in the increase in battery capacity. The reason why the camry hybrid's combined mpg is about 20% less than the prius's is because it weighs 15% more and thus requires more energy (more fuel) to propel. The extra 5% can be explained by the Prius's slightly better drag coefficient.

I think he was talking about the 2012, not the 2013 camry.

Gas Mileage of 2015 Vehicles by Honda

Look at the 2015 Accord Hybrid mileage. Looks like Honda got their act together on that one.

No more Insight?

They dropped the Insight because of poor sales. But there are plenty of new 2013/2014s available.

Whoa, did you see the v6 manual vs automatic MPG? It says the auto gets a whopping 6 MPG better highway MPG over the manual. Honda must have totally ruined the gear ratios of the manual. I'll bet 6th gear is worthless as a gear to accelerate with, as well as worthless as a gear to cruise at steady highway speed.

Very impressive with the hybrid though. 50 MPG from a midsize sedan is excellent.

All those numbers make me sad about my 31 MPG from the TSX.
