Lexus RX 450h - What the Auto Press Says

The 2010 Lexus RX 450h ranks 3 out of 16 Luxury Midsize SUVs. This ranking is based on our analysis of 24 published reviews and test drives of the Lexus RX 450h, and our analysis of reliability and safety data.

For 2010, Lexus has redesigned its RX Hybrid crossover and changed its moniker from 400h to 450h, marking the SUV's second generation. The new model doesn't represent a radical change. Instead, Lexus has refined one of its best-selling vehicles by adding a few needed elements to keep it fresh and modern.

In Truck Trend's comparison test with the Volkswagen Touareg TDI, Mercedes ML320 Blutec and BMW X5 35d, the RX Hybrid placed second. Truck Trend concludes that the RX is "[p]erfect for the iPhone-loving city-stomper, but if long/heavy hauls and more than light off-roading figure into the equation, you'll find it too compromised."

The RX Hybrid's electrically assisted V6 engine has grown from 3.3 to 3.5 liters. Along with more compact batteries and motors, the new engine gives the 450h even better fuel economy than before. It also gets a new rear suspension and an interior that's been redesigned and made more spacious. Overall, it's an even more refined car than before, and one that might be worth it for Lexus loyalists. Because of its good value, the RX Hybrid is our 2010 Best Hybrid SUV for the Money. Still, several reviewers question the 450h's high price tag. It is expected to cost about $7,000 more than its RX 350 counterpart, which is reviewed separately.

• "Although it's not any quicker, the 2010 Lexus RX 450h is a better vehicle than the RX 400h. It's a bit more fuel-efficient, and whether you're accelerating, braking or turning a corner, this hybrid RX is a touch smoother and more refined. It feels more like a normal luxury crossover SUV." -- Edmunds
• "Is the RX450h the right thing to do? Well, you could always get a Toyota Prius and get 50 mpg, so it's more accurate to say the big hybrid ute is less wrong than right. Search your conscience and your wallet." -- Los Angeles Times
• "There are sportier models available, like the MDX and FX35, but if you're looking for refinement and comfortable luxury, the RX remains an appealing choice." -- Cars.com
• "The RX 450h will appeal to tech-savvy buyers looking for a leading-edge powertrain that delivers an unmatched blend of performance, fuel-efficiency and environmental friendliness. Ironically, the 450h also delivers a better driving experience than the RX 350, with the more balanced performance and better low- and mid-range torque provided by the electric components of its hybrid powertrain, so driving enthusiasts also get a better deal." -- MSN
• "There are certainly more entertaining, attractive and powerful ways to transport five people and their weekend getaway gear, but that's never been what the RX is about. Simply put, it's about the destination, not the drive. And because of that, the RX will continue to define the segment without ruffling the feathers of public's consciousness." -- Autoblog

RX-Hybrid Performance - 8.5 (Very Good)

Test drivers love the Lexus RX 450h's performance, which is impressive for a hybrid. Improvements for 2010 have made the transition from gasoline to electric power even more seamless. However, a few test drivers complain about slow acceleration and poor handling due to the hybrid's excessive weight. "OK, so the RX 450h has a pretty long payoff period and is slower than its predecessor," says Edmunds. "But don't go thinking Lexus has lost the plot with the RX 450h. Far from it -- the 2010 Lexus RX 450h is exactly what it needs to be. It rides smoother than ever, and glides free of road hum or wind roar." Read More
