Honda Ridgeline, Ford Ecosport and Tesla profits | Autoblog Podcast #537

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Green Editor John Beltz Snyder and Associate Editor Joel Stocksdale. We talk about driving the 2018 Ford Ecosport and Hyundai Accent. Joel tells us why he loves the naturally aspirated engine in our long-term Honda Ridgeline. We discuss Tesla's profitability claims, Johan de Nysschen leaving Cadillac and a possible date change for the Detroit Auto Show. As usual, we'll also spend a listener's money on a car.

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.

Buckeye Current back on track at Pikes Peak with new rider [w/video]

After suffering a major setback, the Buckeye Current electric motorcycle racing team of students from Ohio State University looks set to take on the 2015 Pikes Peak International Hill Climb on June 28. The squad's longtime rider Rob Barber suffered a crash on the bike during practice for the event. Now, three-time Pikes Peak 450 Pro Class winner Joe Prussiano (pictured above) has taken over to challenge the mountain for the group. In some ways, Buckeye Current is the scrappy underdog of the electric motorcycle racing world. The student team has definitely shown speed, though. In 2013 and 2014, its bikes took consecutive third place finishes in the Isle of Man TT Zero with Barber in the saddle. This year the squad's sights are set on Pikes Peak with a new bike called the RW-3, and the aim is for a possible overall motorcycle record. Utilizing a frame from a Honda CBR1000RR, the students created the 7.8-kWh battery pack, carbon fiber fairing, and electronics system. The team estimates the cycle is making over 134 horsepower and is capable of an average speed of 76 miles per hour up the hill climb. Following Barber's crash, the RW-3 had to be rebuilt, but it has now passed tech inspection to race up the mountain again. Scroll down and check out Prussiano's first ride of the RW-3 on America's Mountain. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. BUCKEYE CURRENT RALLIES TO COMPETE IN THE 2015 PIKES PEAK INTERNATIONAL HILL CLIMB Buckeye Current, the student electric motorcycle team at The Ohio State University, has completed its latest all-electric racing motorcycle. RW-3 will compete in the 2015 Pikes Peak International Hill Climb June 28. This follows on the success of the team's 2013 and 2014 Isle of Man TT Zero performances in which renowned rider Rob Barber piloted the team's RW-2 and then RW-2.X vehicles to third place victories, achieving the title of the world's fastest collegiate electric motorcycle two years in a row. After earning two podium finishes at the Isle of Man, the team was looking ahead to a new challenge. This year the team had to create an entirely new bike to conquer Pikes Peak. RW-3 is designed to average 76 miles per hour through the course with a top speed of 125 miles per hour. The battery pack holds 7.8 kilowatt-hours of energy on board and contains 972 individual 18650 cylindrical battery cells.
