Filed under: Technology , Toyota Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today’s world, is that neither mill boasts direct injection, and both are naturally aspirated. The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren’t going to bore you by explaining just what this is – there’s Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That’s why they’re so popular in hybrids, which can offset the power losses. This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota’s iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

At 8 am Mountain time (9 am EST / 7 am PST), the first of a field of 83 bikes and 63 cars – whittled from an original field of 157 – will race 12.42 miles through 156 turns from the start gate at 9,390 feet to the summit finish at 14,110 feet. The summit is where we’ll be all day, having arrived on the media bus at around 5 am and not allowed to come down until the race is finished. If it’s anything like last year that could mean a 14-hour day on the top munching on donuts at the summit caf
