the new turbocharged variant of the Mazda6, we now know how much more fuel the force-fed family sedan will require. The EPA rating puts it at 31 mpg on the highway, 23 in the city and 26 combined. That is less than the naturally aspirated model with either an automatic transmission or a manual, the former of which gets 35 mpg highway, 26 in town and 29 combined. But the naturally aspirated Mazda6's 184 horsepower and 185 pound-feet of torque are well short of the turbo engine's 250 horsepower and 310 pound-feet.The turbo Mazda6's fuel economy also puts it right in the range of similarly powerful sedans in the mid-size arena. In fact, almost every 2018 2.0-liter turbocharged sedan in the segment gets 26 mpg combined, including Kia Optima, Hyundai Sonata, Chevy Malibu, Buick Regal, and most versions of the Honda Accord, with only a difference of 1 or 2 mpg in city or highway results. The V6 Toyota Camry and Nissan Altima also hit this 26 mpg fuel economy mark.As far as power is … [Read more...] about Turbocharged 2018 Mazda6 EPA mileage figures released
The 2013 Chevrolet Spark now has official EPA mileage numbers to accompany its $12,995 base price. The 2013 Spark with a four-speed automatic is good for 28/37 mpg city/highway while the 2013 Spark with the five-speed manual is rated 32/38 mpg. Those fuel economy numbers may not be class-leading, but the 2013 Spark’s $12,995 base price (including destination) might help some consumers overlook the official mpg numbers. If a majority of buyers go for the four-speed automatic over the five-speed manual, they’ll pay $925 for the transmission and 2 mpg in combined mileage, from 34 mpg to 32 mpg. Potential 2013 Spark buyers not attached to the four-door hatchback body style, but looking for an ultra-low-priced new car, might also consider the 2012 Nissan Versa, which carries a base price of $11,770. If you want the CVT, the base price rises to just under $14,000. The 2012 Versa sedan gets 27/36 mpg with a five-speed manual — below the manual-transmission 2013 Spark — … [Read more...] about 2013 Chevrolet Spark EPA-Rated at 28/37 MPG Automatic, 32/38 MPG Manual
Over the years, we’ve tested our fair share of vehicles, ranging from SUVs to subcompacts and everything in between. With fuel economy one of the main purchasing decisions thanks to rising gas prices, many consumers want to know that their vehicle is going to give them the numbers they want to see. However, some people want the car they want even if it only gets 6 miles to the gallon. We’ve gathered the top 15 models we’ve tested that have significantly surpassed their EPA estimates. Whether it’s an automatic or manual, SUV or sedan, you might be surprised at just how good these numbers really are. Kicking off our list is the 2013 Honda Fit Sport. This hatchback is known for its impressive interior space and competitive EPA mileage rating. As it sits, the manual variant offers a rating of 27/33/29 mpg city/highway/combined, and while those numbers are impressive for a car of this size, you shouldn’t take those numbers at face value. During our Real MPG … [Read more...] about 15 Cars That Get Better MPG Than Their EPA Estimates
calculating EPA mileage, the so-called "coastdown" test, has been tweaked for the 2017 model year. The changes were announced in February, and now that fuel-economy figures have begun rolling in for next year's models, the effects are now becoming evident. Several models lose an mpg or two in highway ratings as a result of the changes, which can effect the combined number as well.The coastdown test is done to calculate the effect of mechanical resistance and aerodynamic drag on the car, which has a direct effect on fuel economy. The effect is most pronounced at highway speeds, which is why many of the EPA number adjustments concern only that figure. Simulating the coastdown test requires a road-force load number to be calculated, and that calculation is what the EPA is adjusting now. The numbers are not changing much for 2017, but this is still something to consider when car shopping, especially when cross-comparing fuel economy ratings from 2016 and prior with 2017 numbers. Here are … [Read more...] about Stricter rules cause some 2017 EPA fuel economy numbers to drop
How the Hell do you calculate the official Environmental Protection Agency (EPA) mileage figures for plug-in or serial hybrids, vehicles that can/will operate in electric-only, charge-sustaining, gas-only and/or blended modes? In a phone interview with TTAC [below], EPA Senior Project Engineer Carl Paulina reveals that the Feds have been working on the problem with the Society of Automotive Engineers (SAE) for the last year-and-a-half. And… they're still working on it. In fact, Paulina reckons it'll be another year, easy, before the SAE committee figures out how to modify SAE standard J1711 to deal with the new technology (the equivalent fuel cell committee met for five years). Meanwhile, I asked Paulina how the EPA measures current [parallel] hybrid MPG stats. The result is a rivet counter's wet dream. Bottom line: your mileage may vary. … [Read more...] about EPA Strugges to Devise Plug-In Hybrid MPG Rating
The Environmental Protection Agency’s current Federal Test Procedure (FTP) for city mileage was originally designed to represent a typical trip on Los Angeles streets. The test– codenamed FTP-72– begins with a cold start from 70 degrees. It then runs for 7.5 miles at an average of 19.6 mph, with a peak speed of 56.7 mph (from a short freeway segment). The EPA Highway Fuel Economy Test (HWFET) starts with a warm engine, runs for 10.26 miles, averages 48.3 mph, and peaks at around 60 mph. Does anyone in the real world drive like that?Obviously not. By the ‘80’s, the EPA was deluged with complaints that its gas mileage estimates were entirely unrealistic (i.e. hopelessly optimistic). In 1984, the EPA reacted by lowering estimates across the board to “more accurately reflect driving styles and conditions.” The government agency trimmed EPA window sticker stats by 10 percent for the city, 22 percent for highway. This overdue amendment helped … [Read more...] about The Truth About EPA Mileage Estimates
One might quite reasonably have expected a smaller, lighter two-passenger variant of the Insight to achieve higher EPA numbers than its bigger brother. Say, like it did in 1989, when the CRX HF pulled a 41/50, compared to the ’89 Civic sedan’s 27/33. But reasonable expectations have been dashed by Honda more often than not lately, as in the Insight’s various shortcomings. But a 31/37/33 mpg combined rating for the new 2011 CRX manual, when the Insight is rated at a 41 combined? Does Honda have a death wish? That highway mileage is the same as the Chevy Cobalt XF, which doesn’t need any stinking battery and seats four. And even the combined mileage is only three mpg better. What gives? Beats me. The CR-Z uses a slightly larger 1.5 version of the Insight’s 1.3 four, churning out 122 hp. But a slightly larger engine doesn’t necessarily equate to worse mileage; on the contrary, the new Prius’ larger 1.8 gets better mileage than the older 1.5. The … [Read more...] about New Hybrid Honda CR-Z Equals Cobalt’s EPA Mileage; Set To Stumble Like The Insight?
TTAC GM Bashing Alert! The following article has been read and reviewed by the TTAC-GM Assault Protective Services Committee and has been found to contain material that may put GM in a negative light. Reader discretion is advised.Unless the elves are asleep at Google, the odds are good that there will be an ad for the 2010 Chevrolet Equinox immediately to the right of this article. And it will proudly trumpet its 32 mpg EPA highway rating, like every other Equinox ad. From GM’s first gleeful announcement, it was hard to swallow from the that a tall, almost 4,000 lb CUV could actually get 32 mpg on the highway, or 26 mpg combined. It appears others are having the same blockage of the pharynx. Now that there’s a number of reviews out, they all show the same pattern: the Equinox EPA numbers are highly deceptive. But would the EPA ever come down on Government Motors? We conducted a survey of independent tests that actually measured fuel economy by comparing miles driven versus … [Read more...] about Why The Chevy Equinox EPA Mileage Numbers Don’t Add Up
Following Ford’s announcement that they will revise downward their advertised fuel economy ratings for the C-Max Hybrid, the United States Environmental Protection Agency said that the discrepancy between rated and real world fuel mileage was not the agency’s fault and appeared to be placing the blame on Ford for relying on the agency’s own rules, substituting data derived from the Fusion Hybrid because it shares a drivetrain with the hybrid C-Max. The EPA’s chief automotive regulator, Christopher Grundler, said that when they tested the Toyota Prius and Hyundai Sonata hybrids this summer, “It was fall quite reassuring.”Grundler told Automotive News “The problem here is really not how the testing is done.” Grundler appeared to have been responding to Ford’s Raj Nair, global head of product development for the Dearborn automaker, who earlier said, “This is an industry wide issue with hybrid vehicles. We’ve learned along … [Read more...] about EPA: Blame Ford, Not Us, For C-Max Hybrids Not Reaching Mileage Ratings
“America’s minivan segment generated only 3.4% of the U.S. auto industry’s new vehicle volume in 2014, down from 5.2% in 2007.”So said I earlier this week in my review of the updated 2015 Toyota Sienna, the only remaining all-wheel-drive minivan.The Sienna was America’s top-selling minivan in each of the last three months. And although the accompanying chart displays its official EPA mileage ratings at 16/23 mpg on the city and highway, front-wheel-drive Siennas are rated at 18/25. Forget the 14.4 mpg we saw during our test. Temperatures were brutal, the vehicle spent much of its time idling as we attempted to clear it (along with every other car on the street) of multiple inches of ice, the city streets on which the Sienna spent most of its stay were mostly snow-covered, and the van was fresh off the assembly line.But could we have reasonably expected more than 16 mpg in city driving? Not according to the EPA.A 2005 all-wheel-drive Sienna was also rated … [Read more...] about Chart Of The Day: Is Minivan Fuel Mileage A Big Part Of The Problem?
