Honda protective of Type R name; NSX Type R not in the works

During a roundtable during a recent event hosted by Honda, we joined in on a roundtable interview with Honda Technical Consultant Ko Yamamoto and Honda Civic Type R Project Leader Hideki Kakinuma. Questions were asked about the Type R brand broadly, as well as the potential for some new projects. The answers were both good news and disappointing news for Honda fans. The good news is that Honda takes the Type R name and brand very seriously. Yamamoto and Kakinuma explained that the name and its associated red "H" badge are only for vehicles with a racing connection, such as the Honda Civic Type R that has a couple of racing variants. As such, you won't be seeing a CR-V, Odyssey or Insight with the Type R name. Furthermore, the Type R name is only for Honda-badged vehicles, despite the existence of the Acura Integra Type R a couple decades ago. We also asked about the potential of an NSX Type R, which certainly meets the performance and racing credentials mentioned, but is much more of an Acura product and is badged as such in the U.S. Kakinuma and Yamamoto couldn't go into deep detail, but they said that there aren't plans for one at the moment, and the chances of one for the U.S. are unlikely. They noted that the previous NSX Type R was a Japanese-market exclusive, and if such a car did come to fruition, that might be the case yet again. Kakinuma did say that if he was the one in charge of NSX, he would have already had it in the works. So it's not impossible that there could be an NSX Type R in the future, but don't look for one anytime soon. Related Video:

Acura organizes new business division to confront falling sedan sales

Honda and Acura North America have announced a major restructuring of operations in hopes of turning around Acura's flagging business. For 2013, sales for Acura's sedans dropped 10.4 percent, while its CUV sales grew by 21 percent. The newly formed Acura Business Planning Office will attempt to right the ship.
As part of the restructuring, Acura is promoting Erik Berkman from President of Honda R&D Americas to lead a new division called the Acura Business Planning Office. Berkman has been with Honda since 1982 and led development of the 2006 Accord. He was also the first US engineer to head North American research and development and has been head of Honda Performance Development since 2008. "Erik's appointment to the new Acura Business Planning Office is a clear indication of the high priority we place on Acura," said Honda spokesperson Jeffrey Smith to Automotive News.
American Honda Motor President and CEO Tetsuo Iwamura is also going to be working to improve the business. He has been elected chairman of American Honda's board, and has simultaneously taken the new position of Corporate Brand Officer to improve the management of the company's brands.

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.
