One significant oversight is stop
start technology. Overseas stop-start technology is
featured on a host of models, including the Audi A3 TDI, BMW
1-Series, BMW 3-Series, Mazda
2, Mini Cooper, Toyota Yaris. The technology is somewhat
expensive -- it's about $500 extra to install -- however, it's more
than worth it, providing fuel economy gains of around 7 percent.
EPA's flawed test cycle, though, currently only includes one stop so
the tech only earns automakers a 0.1 or 0.2 mpg increase in the
official EPA mileage estimates, despite much larger real world
gains. Without the extra rating to justify the extra costs,
manufacturers simply haven't been importing the tech on U.S. models.
Currently, the only vehicles to feature the tech are hybrids such
as the Toyota
Prius, Honda Insight, Chevrolet Malibu Hybrid and BMW
ActiveHybrid X6, as their electric systems allow the tech to be
implemented at a much lower costs. The net result is that at
the end of the day, the U.S. is trailing the rest
of the world in fuel economy.
Still the allure of models
like the Volkswagen Lupo, which received an estimated 75 mpg, keep
customers demanding that the EPA reconsider stop-start. Robert
Davis, Mazda's top product-development executive in North America,
comments, "In Japan, we're seeing anywhere from 7 to 9 percent
fuel economy gains from it. That's a jump from 33 to 37 miles per
gallon in a metro environment."
Audi of America spokesman
Christian Bokich complains, "We did not realize any savings in
U.S. EPA estimates based on required testing cycles."
EPA may finally be coming around and may try to fix its flawed test
procedure. It's taking public comment on stop-start
technologies, currently, and will look to announce new procedures in
April. Those procedures could finally include a test with more
stops. Mazda is urging automakers to join together to lobby the
EPA to give stop-start its just rewards. While this is
obviously a matter of personal interest to the company, it's also
important industry wide, and to U.S. consumers.
quote: Yet, when the cost is actually revealed for this $500 stop/start mechanism that will save real money and fuel, it begs to question who is making these decisions saying something is expensive. GPS and entertainment packages usually add $2000-5000 to a car. Do people really need the $500 wheel package? Is it expensive because the diesel Accord would have needed a $75 oil change versus $25?
quote: Its the consumer who makes the decision ultimately. The people looking for a big increase in fuel efficiency are typically buying cheaper, more fuel efficient cars. Sure, there are the groups who buy a Fusion hybrid, Prius, Escape hybrid...but lets be honest here. Those buying those care are really doing it more for a "feel good" perspective, rather than actually spending that much more money to save fuel.
quote: The car may be better, and you may get another few miles per gallon (what, 3 or 4?) with the hybrid...but if you were really all that concerned with gas mileage, you probably wouldn't be driving an SUV...and if you were concerned with both costs and mileage, you sure wouldn't have bought a hybrid SUV.
quote: My Highlander hybrid is getting 26 MPG combined.
quote: My bro in law bought a Highlander late last year and could not justify the nearly $12k increase in price and mediocre increase in gas mileage over the regular Highlander. His other car is a Camry Hybrid btw.
quote: When I equip the standard Highlander to a level very close to the Standard Higlander Hybrid I get a premium of more than 6,000 dollars and an EPA estimated difference of 3 MPG or ~ 0.5 gal per 100 miles.
