The new 1KR-VE engine now features variable-valve timing with intelligence (VVT-i) on the intake valves. Several minor changes and refinements were also introduced for increased fuel efficiency and more linear power delivery. Notable changes include a higher 11.5:1 compression ratio, a high-tumble intake port, a longer intake manifold, micro fuel spray injection and low-friction valve lifters.
