Lexus Rx450H+ vs Hyundai Genesis

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

The Genesis is not quite a match for cars twice its price but it makes you think what's possible. It doesn't have the dynamic brilliance of a BMW or the self-assured faultless execution of a Mercedes. Lexus ought to be worried, though - why would you have an LS when you could have this? The only answer is 'badge'.

The Genesis is an epoch-making car for the Korean manufacturer. As the company has got better, there are fewer excuses for overlooking it. While the Genesis is pitched into a shrinking market, it's not really meant for the average i30 buyer to buy, but to see.

It's bristling with tech and is not only a halo car but a shot across the bows of both Lexus and the Germans. Attached to that shot is a note: "We're coming for you." In other words, Hyundai got it right.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

The Genesis is like no other Hyundai. For a start, it's gigantic - it looks easily as big as a BMW 7 Series (it isn't) with the road presence to match. There's a lot of BMW from most directions, but with a sharper approach to the creasing and character of the sheet metal.

Towards the rear it's more BMW 6 Series Gran Coupe and is all the better for it. The style is understated and technocratic.

Inside is also very Germanic, but with a bit more of a Lexus feel

The big wheels from the Ultimate pack help make it look lower and sleeker, too.

Inside is also very Germanic, but with a bit more of a Lexus feel. Our car had the lighter leather which meant that the wood and the metal materials didn't necessarily work well together.

The interior is expertly put together and feels like it will last forever.

The only jarring moment is the gear selector is shared with our long-term Hyundai i30 - it looked a bit cheap in what is otherwise a beautifully executed cabin - it needs more heft.

On Australian-delivered cars there is just one Hyundai badge, sitting proudly on the boot - you get the feeling this was debated long and hard and when the decision was made to go for it, a big one was chosen.

However, the winged Genesis branding takes pride of place everywhere else. When you approach the car at night and the puddle lamps come on, the Genesis logo is projected on to the ground, crisp and clear.

The only way to describe the Genesis' pricing is aggressive - kicking off at $60,000, it's the most expensive Hyundai money can buy, but with a spec list like this, you won't feel at all short-changed.

Your sixty large buys you a huge cabin with a seventeen speaker stereo, auto headlights and wipers, LED ambient lighting inside and out, dual-zone climate control, keyless entry and start, powered front seats which are heated and cooled, satnav, front and rear parking sensors, and plenty of other bits and pieces.

Our car had the $22,000 Ultimate package, adding 19-inch alloys, blind spot sensor, front and side cameras, around-view display, real leather, more adjustments for the driver's seat, ventilated seats in the front, heated rear seats, panoramic glass sunroof, acoustic glass, heads-up display, powered bootlid and LED foglamps.

The Genesis is like no other Hyundai

You can have a lot of the more useful features in the $11,000 Sensory Pack. It's a good middle ground that, for example, features the excellent heads-up display.

The 9.2-inch screen splits the asymmetric air-conditioning vents. The software is unique to the Genesis and a huge leap forward over the rest of the Hyundai range - classy, smooth graphics, a good responsive screen.

You control the seventeen speaker stereo from here, which kicks out a rich sound and an impressive Bluetooth performance - rear seat passengers can also run the stereo from their armrest. The satnav is detailed and chatty, while the excellent heads-up display shows a configurable information set in strong, clear graphics.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

The Genesis is powered by Hyundai's own 3.8-litre V6 developing 232kW and 397Nm, mated to Hyundai's eight-speed automatic transmission.

Despite weighing just under two tonnes, the Genesis completes the dash to 100km/h in 6.5 seconds.

It has a claimed 11.2L/100km on the combined cycle. In what must be a first, we got below that, averaging 10.8L/100km over two weeks. And that's without stop-start fuel-saving to blunt the effect of lot of city driving.

The Genesis is not going to tempt you into a track day, even with rear wheel drive

We'd still like to try the V8 - only available in left-hand drive markets - though.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

At five metres long, with a ride firmly pitched in the luxury camp, the Genesis is not going to tempt you into a track day, even with rear wheel drive.

Blindfold your passengers and swap them between a Lexus, a BMW and a Genesis and the overwhelming impression they'll get is one of incredible smoothness.

If you're wanting sudden movements, this isn't the car for you

Sitting in the back of the Genesis, it's easily as good as the German and luxury Japanese competition. The seats are hugely comfortable, there's ample head, leg and shoulder room and it feels lot nicer than anything within a bull's roar of its price.

No matter where you sit, it's an incredibly quiet car. The engine is a distant whoosh, the tyre noise muted and there's almost no wind or ambient noise. It's supremely comfortable and the excellent stereo will wash away what little noise does invade.

It certainly feels its weight from the driver's seat, with a competent, soft turn-in, but if you're wanting sudden movements, this isn't the car for you.

The Genesis is an epoch-making car for the Korean manufacturer

On fast flowing roads you can have some fun, but things will get floaty and that will quickly kill that fun. The ride and isolation from the rest of the world is completely worth it.

Nine airbags, traction and stability control, lane departure warning, forward collision control, ABS, brake force assist and distribution and traction and stability control bring the ANCAP count to five stars.

The Sensory and Ultimate packs add blind spot sensors and around view cameras.
