Honda Accord Hybrid falls well short of 47 mpg, says Consumer Reports [w/video]

Do not poke Consumer Reports with the hybrid fuel economy stick. That seems to be the lesson illustrated here yet again. The Honda Accord Hybrid is the latest to arouse the ratings bear, returning "just" 40 combined mpg in CR testing. Even so, that makes it "a class leader for fuel economy among midsized sedans," besting even the Civic Hybrid in CR testing, but that's still a lucky roll of the dice short of its EPA rating of 47 mpg. Remember, it was back in December 2012 that CR knocked the Ford Fusion and C-Max hybrid models for the exact same failing: certified with an EPA-rated 47 mpg but delivering "just" 40 mpg.
Beyond that, while the Accord Hybrid earned a lower overall score than the traditional gasoline Accord because of its ride, handling and refinement issues, it gets unqualified applause from the institute for its "very impressive hybrid system."
It will be interesting to see if CR's findings will negatively impact the model's sales, which to this point have been impressive enough that demand is outstripping supply. In the meantime, you can check out CR's brief video review of the Accord Hybrid below, and check out the magazine's press release chiding its mpg rating.

Honda patents engine with different cylinder displacements

A basic rule of engine design states that the displacement of a cylinder is equal to the engine's total displacement divided by its cylinder count. Honda, according to a recently surfaced Japanese patent, is looking to break that rule with an engine containing cylinders of different sizes. We've done our best to translate it from patent-ese. The idea is that different-sized combustion chambers give more flexibility when any combination of cylinders are deactivated, or rested. Because the different numbers can be combined in various ways, it provides more and smaller increments than would an engine with equal-displacement cylinders. Take a 2.0-liter four-cylinder, for example. Following the golden displacement rule, each of the four cylinders has a volume of 500 cc, giving displacement increments of 500 cc when any cylinder is deactivated. But suppose instead that the four cylinders displace 300, 425, 600, and 675 cc, respectively. This would give the engine 15 available displacements instead of just four, and the spacing between each option would be far less than 500cc. As a result, those different virtual displacements would provide more adjustment between power and efficiency than a cylinder-deactivation system can on a conventional engine. Honda's patent describes cylinders with equal bore size, with the displacement from cylinder to cylinder varying based on the crank throw radius – the longer the throw, the longer the stroke and the larger the displacement of that particular combustion chamber. The patent describes how the cylinder sizes would need to be arranged to spread the load on the crankshaft and presumably limit vibration that would be introduced by the different pulse magnitudes. If we're interpreting things correctly, the largest cylinder (the one with the longest crank throw radius) sits in the middle of the bank with the smaller ones alternating on either side as they decrease in displacement. This concept is described for multi-cylinder inline and V-type engines of various sizes. The patent was filed in March of 2014 and published in January of this year. Whether or not this arrangement will reach production is of course unknown, but the advantages in terms of both efficiency and power seem promising.

How Seinfeld hopes he'll help industry make better car commercials [w/video]

Bloomberg has a fascinating look into a web series that continues to be a favorite around the Autoblog offices - Jerry Seinfeld's Comedians in Cars Getting Coffee. The series, which is in its second season, sees the affable comedian picking up fellow comedians in a range of interesting cars, and having conversations with them over the drive and a cup of joe.
The piece by Bloomberg dives into the development of the series, as well as Seinfeld's tie-up with Acura, which saw the Honda-owned brand begin sponsorship this season. That relationship started not with his web series, though, but with a Super Bowl ad, alongside fellow funnyman and car enthusiast Jay Leno, that saw them competing over a new Acura NSX. Have a click over to Bloomberg for an entertaining piece that looks beyond the YouTube series. We've also wrangled Seinfeld's original Super Bowl ad for the Acura NSX, which you can see below.
