Subaru has stuck with all-wheel drive exclusively in the U.S. The rear-drive Subaru sports car will be a departure for the brand in the United States when it goes on sale here next year. That's a big savings in an industry where saving a single kilo (2.2 pounds) is a big deal. Because of those factors, the boxer weighs close to 50 pounds less than a comparable inline four-cylinder, he said. Masuda said the horizontally opposed movement of the cylinders in the Subaru boxer eliminates the need for balance shafts, which would have been needed in other engines. Flat-four engines are mostly used in cars (particularly in the earlier Volkswagen Type 1 to 4 and by Subaru 2 in most of their models), and have occasionally been used in motorcycles. However, Subaru says weight, and therefore fuel savings, were additional reasons the partners used the boxer four. Since Subaru offers all-wheel-drive models exclusively in the United States, we're not used to equating the Subaru boxer engine with better fuel economy. Wassim Kanoun, Toyota Motor Europe product communications manager, said the two cars share 95 percent in common. On the other hand, a second generation of Toyota's version made its debut at the Geneva show as the Toyota FT-86 II concept.

That placement is almost five inches lower than where a conventional I4 would have been, and lower in the car than any car this side of supercars such as Ferrari, he said. Masuda said the boxer engine's flat profile allowed the partners to place the engine's center of gravity "this high," gesturing at his knees. "The boxer engine is lightweight, compact and has a low center of gravity," he said at the Geneva motor show. "Form follows function," said Toshio Masuda, Subaru's senior project general manager for the Subaru-Toyota joint venture. Subaru is proud that Toyota picked a Subaru boxer engine for the rear-drive sports car the brands will share starting next year.
