Acura RL 2nd Gen (KB1)
World's first car with active torque-vectoring AWD. Technically important, commercially obscure.
The 2005 RL is genuinely historically important: it introduced SH-AWD (Super Handling All-Wheel Drive), the world's first all-wheel-drive system with active rear torque vectoring — a technology now found across Acura's lineup. The J35 V6 made 290 hp in early cars, rising to 300 hp from 2009. Six-speed automatic from 2009. Standard adaptive cruise control with collision mitigation, 8-speaker Bose audio, real-time AcuraLink traffic. The technology was ahead of its time, but the RL never sold well — the styling was conservative, the price was steep, and luxury buyers had stronger badges to choose from. Production ended in 2012, replaced by the RLX. Now an interesting used buy if you appreciate the SH-AWD pioneer.
