2017 Lexus RX 450h hybrid Complete In-depth Review & Buying Guide

Hybrids, hybrids, hybrids. That’s all that people in the auto industry ever really talk about these days. Your favorite hypercars are hybrids, your neighbor’s Prius is one and some luxury sedans too. But you don’t hear a lot about “hybrid SUVs” in the world. Well, that’s because 4WD powertrains already weigh more than most alpine ranges and the addition of an electric motor would only mess up the overall efficiency. Or does it? Here’s the 2017 Lexus RX450 h to prove us all wrong…

The RX450h houses a 3.5 liter V6 combined to no lesser than three electric motors. This complex unit is mated to a CVT transmission and makes around 308 hp and 247 lb-ft of torque which are healthy figures for a mid-size SUV. The RX has been here since 1998 but the previous four generations didn’t really make a revolution in the market so this is their chance at redemption.

Overall Rating

The RX450h is accompanied in this segment by the BMW X5 xDrive 40e and the Mercedes Benz GLE 550E 4 Matic, both of which are comparatively more established cars than the Lexus. With a starting price of $53,035, the Jap-American hybrid SUV is cheaper than the rivals but could it possibly challenge the technological prowess of the Germans?

2017 Lexus RX 450h hybrid Engine


The 2017 Lexus RX Hybrid gets excellent fuel economy and delivers a smooth and comfortable ride, though its steering is a bit slow to react. There is little difference in performance between this luxury midsize SUV and its gas-only version. It has strong acceleration and smooth transitions from electric to gas power. – cars.usnews

Engine and Transmission

What puts the RX450 h into motion is a very complex hybrid powertrain consisting of a 3.5 liter V6 along with three electric motors. The system pumps out a total of 308 horses sent to all four wheels and generates 247 lb-ft of torque.

In comparison to the X5, that is a lot more oomph but the GLE somehow makes a ridiculous 362 hp and 384 lb-ft of torque making it the undisputed leader in this department.

MSRP $53,035 $63,200 $66,300
Engine 3.5L 6cyl 2.0L 4 cyl 3.0L 6cyl

The RX is less of a fatso than its rivals meaning it weighs lesser so that’s supposed to mean better acceleration, right? Well, wrong. The figures aren’t terrible as such but the lesser weight definitely makes you question how it’s less quick than its rivals.

It may have something to do with the rivals having better-engineered transmissions as opposed to the lame CVT available in the RX450h. 0-60 MPH happens in 7.8 seconds and the quarter-mile takes 15.1 seconds to be completed.

The quickest car here is the X5 surprisingly because it is both underpowered and heavier compared to the RX. The GLE isn’t so bad either and is the quickest in the quarter mile run at 13.7 seconds.

Engine 3.5L 2.0L 3.0L

The RX450h handles just like its non-hybrid sibling around corners and we’re specifically talking about the new AWD version because the old FWD was discontinued for reasons unknown (maybe because it handled like a Yaris? ). But it is clear that the power going to all the wheels is the right direction to go for this new model because there is a great amount of stability and eagerness to get into tight corners which becomes more appreciable as you get used to driving it.

There is a tiny bit of under-steer at high speeds but even that is eradicated in the sublime F-Sport package which offers a sportier and refined ride. The suspension becomes stiffer in this trim and makes you feel like you’re driving a performance hatchback instead of a 4-tonne SUV.


Where the lesser weight really accounts for something is the 60-0 braking distance which is nothing short of exceptional. The Hybrid SUV comes to a complete stop from 60 MPH in just 125 ft. making it better at braking than both the Germans here. In fact, the X5 takes 165 ft to come to a stop due to the extra weight. The GLE 550e is the closest rival to the RX450h here as it comes to a complete stop in 130 ft.

The brakes in the front are 12.9 inches and the ones at the rear are 13.3 inches in diameter. Here is a detailed look into the braking figures of the SUV in comparison to its rivals -

The pains of combining that traditional V6 with three electric motors definitely paid off as the fuel economy figures are simply exceptional. Efficiency was obviously expected but this takes the car to the top of the throne in the hybrid SUV market.

In the city, you can expect to get 31 miles to the gallon and on the highway, around 28 MPG which means you get a combined MPG of 30 making it the most efficient car in its class.

2017 Lexus RX 450h hybrid Interior


The 2017 Lexus RX 450h's cabin is great to look at and beautifully made. It's a real standout in the segment. However, some controls are difficult to use and the backseat isn't as generous as those of some rivals. - Edmunds

Seating and Comfort

Craftsmanship basically went into overdrive in the interior of the RX450. Everything from the stitching to the way the door handles feel is premium and manages to distance itself away from minimalistic Toyota interiors. Every detail of the car and the materials used are exquisite and a few years ago, you could only expect such extravagance from a Maybach or Rolls-Royce.

The seats are beautifully crafted and provide exceptional thigh and back support to each of the five passengers riding inside the RX. There is also a 3-row model which could be yours in order. There is tons of legroom and headroom guaranteeing reduced amounts of exhaustion during long drives.

2017 Lexus RX 450h hybrid Exterior


Terms like “bold,” “aggressive” and “highly styled” all describe the 2017 Lexus RX’s look. “Polarizing” is another. Keeping with the rest of the Lexus lineup, it begins with a gaping “spindle” grille up front, fluid headlight housings with LED lights, a high beltline, and the 2017 RX’s most divisive element: a flowing, blacked-out C-pillar behind the rear windows. - Kelley Blue Book

Dimensions and Weight

Okay, you might have read earlier that we found the new Lexus RX to be a well-designed car even though it’s not conventionally beautiful or elegant like a Beemer X5 or a Merc GLE. Those cars are obviously good looking but let’s face it, they’re boring. They fail to capture your attention like the RX does with its ludicrous design with weird shapes, the spindle grille, and helmet-shaped roof.

You can’t deny that this car is infinitely more interesting to look at than the other two and it’s a bold step from Lexus to stand out from the crowd. Cars should be about individuality and here is the RX taking it a step further. This is exactly why we feel obligated to appreciate the design due to the sheer creativity and fun of it.

2017 Lexus RX 450h hybrid Competition

Lexus RX450 h vs BMW X5 xDrive 40e

Before the introduction of the X6, the X5 was the one German SUV everybody took seriously and it even paved the way for brands like Audi and Mercedes Benz to come in with more competitive sub-compact luxury SUVs. From the numerously available trims in the X5 line-up, the xDrive 40e is the efficiency-centered hybrid variant.

It looks macho and aggressive on the outside but on the inside, the technological sophistication completely contradicts the vibe from this large SUV. If the RX is too wild for your taste, this stays right below that and has a more appealing design with similar benefits although at a much higher rate. At the end of the day, the RX triumphs over it in terms of value for money.

Lexus RX450 h vs Mercedes GLE 550e 4Matic

If the new GLE reminds you of the ML, you’re not wrong as it is basically the same car with revised mechanicals and now a hybrid powertrain. It got AWD (Merc calls it 4MATIC) and is a better off-roader compared to the RX450h and the X5. This is the most expensive car in its class and starts off at an eye-watering $66,300 for relatively the same features and tech as the Beemer and the Lexus

It is powered by a 3.0 liter V6 and an electric motor which together makes 362 hp and 384 lb-ft of torque. The interior has been hugely improved and has tough guy characteristics reminiscent of a G-Class SUV. If greater off-road performance and road presence are on your list of priorities while buying an SUV, then this will suit you better than the RX450h.

2017 Lexus RX 450h hybrid Final Verdict

The older RX models were good sellers and had managed to bring in a lot of revenue for Lexus but for enthusiasts and SUV buyers, it was easily replaceable or was usually a stepping stone for more exciting things. This one, however, is a proper luxury SUV inside and out and the German alternatives are gonna have a hard time convincing to-be customers to move away from the Lexus.

The interior is gorgeous, the ride is blissful, the performance is sufficient and it looks like nothing else out on the road. Plus, it obviously has a better resale value than the X5 and the GLE. In conclusion, the RX450h is an all-rounder and a force to be reckoned with in this segment.
