Cadillac Optiq vs Lexus NX450H+

What's the difference?

A taste test, but so far so good for the Cadillac Optiq, which is already my favourite model in the Caddy range. More space than you think meets a lovely cabin experience and a punchy powertrain.

The Lexus NX450h+ F Sport is a gorgeous mid-size SUV that combines great specs and a fairly efficient plug-in hybrid powertrain. It’s a comfortable and easy ride which should appeal to a wide range of driving styles. It also looks good parked at the kerbside of a city street and with it ticking most of the boxes, it may become your new best friend.

I really like the exterior of this Optiq, and especially the front-on view, with its vertical DRLs and that bold Cadillac grille delivering real medium SUV street presence. 

You could argue the side profile is a little more vanilla (discounting the big wheels, of course), but it looks swept-back and sporty, and not as though it has been designed exclusively for aerodynamics above all else. That's a compliment, not an insult. Cadillac's engineers say every line and crease has been developed to help it slip through the air, but it does it without looking like a science experiment. 

The material choices inside are lovely, too. The brand says it has focused on sustainable and recycled materials (the centre console is made from tulip wood and recycled newspaper, for example), but the highlight in my test car was the fabric derived from recycled polyester fabric that lined the door panels and much of the dash. It's a refreshing (and comfy) departure from the norm.

Less positive is the level of Mar-a-Lago bling dotted elsewhere in the cabin, like the chrome ringed centre console and silver-tipped vent controllers. They jar with the otherwise dark, calming and modern-feeling space.

There are physical buttons galore, controlling all your climate settings along with steering-wheel controls as shortcuts for key functions, but there is also still a bit of on-screen action for things like quick access to your driving modes.

The tech looks fab, though, with the curve through the screen looking intentional and elegant and way nicer than the tablets plonked in a lot of EVs these days.

The NX simple looks like a scaled-down version of its larger RX cousin, so if you like that you’ll like what the NX.

It looks sweeter, though, with its smaller proportions being only 4660mm long and 1670mm high but there’s enough sharp pleating in the panelling and rear LED lights to give it a sporty edge. It’s a design that should appeal to a wide range of people.

The interior helps the NX compete against some of its flashier rivals, but the BMW X3's interior beats it hands down with the wow factor. Still, the dual-toned leather upholstery and fabrics of our test model scream understated luxury.

The perforated leather of the seats is supple underhand, but even the robust synthetic leather on the backs of the seats and some door panelling feels like the real stuff most of the time.

The dashboard components – like the air vents, displays and accents – are well integrated and seem well-built. The cockpit is intimate and plush overall, and it always reminds you that you're in the cabin of a luxury vehicle.

The Cadillac Optiq is around 4.8m long, 1.9m wide and 1.6m high, which is slightly longer than your average mid-size SUV. And I would argue most of that extra space is located in the back seat, where – at 175cm – I had no problem stretching out behind my own driving position. There was plenty of knee room and, thanks to a virtually flat floor, no bulky tunnel getting in the way for the middle-back rider, either.

Headroom could be a touch more challenging. It was no issue for me, but there wasn't a ton of clear air between the top of my head and the raked roofline, so six-foot-plus passengers might be stooping. Still, if your kids are six-foot-plus, get them into the NBA and have them buy you a car instead.

Elsewhere in the back there are cupholders in the pull-down seat dividers, ISOFIX attachment points in each window seat and twin USB-C ports. There are air vents but no temp controls for backseaters.

The boot is sizable, too, with Cadillac promising 744 litres of cargo space with the rear seats in place and 1603 litres with the rear seats stowed flat. And kudos for not just providing a neat charging cable space under the boot floor, but also giving you a little zip-up suitcase to store it in.

The cabin of the NX is spacious where it needs to be for four adults to be comfortable on a longer journey, and features enough equipment to satisfy most.

Access is best at the front because of the wider door apertures and while still easy enough to get in and out of from the back, the rear wheel arch cuts into the aperture a bit.

The front seats are very comfortable with thick padding, tall side bolsters that lock you into place in a turn as well as heating and cooling functions.

The back seats are almost as comfortable as the front! However, the outboard seats offer the best under-thigh support. It is a shame that they miss out on heat functions for its grade level, though.

Storage is fairly good for the class, with lots of small item cubbies up front like a sunglasses holder, a mini drawer next to the drivers' knee and a dedicated phone holder and two cupholders. The large glove box (that can hold more than just a manual) and mid-size middle console shoulder most of the storage burden, though.

In the back you get a couple of map pockets, small storage bins and two cupholders. which is most than enough for this size of SUV.

The boot offers an impressive 520L of capacity and a level loading space makes it an easy car to slide larger gear in and out of. The little storage compartment under the floor is handy for charging cables and the hands-free powered tailgate is always handy to have.

The technology is a nice mix of easy-to-use and high-end with a responsive touchscreen on the 14-inch multimedia display. The system has built-in sat nav, wireless Apple CarPlay and Android Auto. The CarPlay was simple to set up and has maintained a steady connection with my iPhone this week.

Charging options are decent with two USB-C ports and a 12-volt socket per row, as well as a wireless charging pad up front.

With a price hike of almost $6K, our flagship NX sits at $95,900 before on-road costs, but it's still slightly more affordable than its top-grade plug-in hybrid rivals.

The Volvo XC60 Ultra is priced from $101,390 and the outgoing BMW X3 xDrive30e sits at $102,500.

In the flagship variant, the standard features list is well-rounded to include both practical and luxury equipment. There are electric front seats with heating and cooling, an F Sport steering wheel with heating and touch controls, a sunroof, rear privacy glass, and a power-adjustable steering column.

Other items include a powered tailgate with a kick-to-open function, dual-zone climate control with a humidity sensor, parking assist, keyless entry/start, a digital key, Lexus Connected services app, a digital rearview mirror and 20-inch alloy wheels.

The technology looks gorgeous with the 14-inch touchscreen multimedia display taking centre stage with built-in satellite navigation, Bluetooth and wireless Apple CarPlay and Android Auto.

You also get a 10-speaker Lexus premium sound system, which has AM/FM radio, MP3 and WMA (Windows Media Audio) compatibility. There are four USB-C ports (2/2), a 12-volt socket and a wireless charging pad.

So while our test model misses out on some of the items you might expect to see for a top-model grade – like three-zone climate control and heated rear outboard seats – it still feels well-specified.

There is only one trim level and powertrain on offer in the Optiq, called the Sport AWD, and with it comes dual electric motors – one on each axle – delivering a total 224kW and 480Nm. 

That's enough, says Cadillac, to push the Optiq to 100km/h in a hot-hatch-feeling 6.3 seconds and on to a top speed of 210km/h.

The NX450h+ F Sport is the first attempt at a plug-in hybrid powertrain for Lexus. It pairs a 2.5-litre four-cylinder petrol engine with two electric motors, one located at each end of the car for all-wheel drive. Together they produce up to 227kW of power, but Lexus doesn’t quote the combined torque figure (cheeky).

The flagship model can do a 0-100km/h sprint in 6.3 seconds and features a smooth continuously variable transmission.

Overall, it moves quickly and the shift between the electric and engine components is barely noticeable.

The downside of the Cadillac EV experience arrives here, with surprisingly slow charging speeds for a vehicle in this class. Remember, Australia's fastest DC chargers are rated to 400kW, and a vehicle like the BMW iX3 will accept it, taking you from 10 to 80 per cent charged in 21 minutes.

The Optiq, though, is rated to just 110kW, which feels a bit odd. The brand doesn't quote a 10 to 80 per cent time and instead says you'll accrue "up to 94 kilometres of range in 10 minutes".

Still, most people charge at home, and there the Optiq can be plugged into anything from a regular wall socket to a super-fast 22.1kW three-phase AC wallbox. 

The brand is promising a total 425km WLTP driving range with a fully charged battery.

The flagship NX has a smallish 18.1kWh lithium-ion battery and a Type 2 charging port but no CCS enhancement, which means you can’t hook it up to a fast DC charger.

On a standard AC 240-volt domestic plug port, you can charge this from 0-100% in around 7hrs 30mins. You get a great electric-only NEDC-rated driving range of up to 87km and that means you really only have to charge it every other day, which I appreciated. 

The official combined fuel cycle usage is 1.3L/100km, but you won’t really see that in the real world. After doing some longer trips mixed in with city slicking, my average real-world usage popped out at 6.5L/100km, and I averaged 20.2kWh/100km when in pure EV mode. They’re not the best hybrid figures I’ve seen for the class, but they're not too bad either.

First things first, this was a limited test of the Optiq, mostly stop-start Sydney traffic, so you’ll have to wait 'til we get the Caddy through the CarsGuide garage for a full and thorough test for a detailed driving review. But on first impressions, the signs are good for the Optiq.

The power delivery is rich and plentiful, and while it’s not aggressively fast, there’s more than enough punch from the line to get you up and moving in traffic.

It rides well, only feeling a bit brittle over properly rubbish road surfaces, and it offers a refreshing sense of connection to what’s going on beneath the tyres.

The steering can feel a little vague on-centre, however beyond that it feels direct but not darty, with a nice weight to the movement. 

The active noise cancellation and sound deadening appear to be doing their roles well, too. I drove past a roadworks site, and most of the drilling occurring outside was banished from entering the cabin. Impressive stuff.

Again, I want to spend more time with the Optiq before passing full judgement, but so far so good – it's my favourite of the Cadillac products to date.

This NX feels like it has lots of power in reserve when you put your foot down and never struggles going up big hills. When it’s in pure EV mode, it’s very quiet but there’s no big fanfare when this kicks over to the traditional engine. You barely notice it until you’re on the open road travelling at higher speeds, and that’s when the engine starts to sound more growly like its non-hybrid siblings.

The steering is forgiving without feeling too light and around town, the NX is nimble and sure of itself. The suspension is on the firmer side, so you’ll hear and feel the bigger bumps, but it never feels rough.

Visibility is decent with the largish windows, and the pillars that aren’t too wide from my driving position. I do like having the digital rearview mirror, though, because when you have a big car seat or tall adult in the back seat, the vision back there is hindered.

It’s pretty hard to find a modern car that’s terrible to park, especially in the mid-size SUV segment, and the NX is no different. Even in a small car space, you still have good clearance around you, which hopefully translates to less dings from neighbouring cars!

The 360-degree view camera system is top notch with its quality, and I like that the car disappears and you can see the ground underneath.

The NX comes with a maximum five-star ANCAP safety rating from testing done in 2022 and scored very highly across its individual assessment scores; 91 per cent for adult protection, 89 per cent for child protection, 83 per cent for vulnerable road user, and 92 per cent for its safety assist systems.

Eight airbags are standard which includes a front centre airbag and driver's knee airbag. 

Other safety equipment includes emergency steering assist, blind-spot monitoring, lane departure alert, lane-keeping aid, emergency lane keeping, traffic sign recognition, safe exit assist, rear cross-traffic alert, LED daytime running lights, LED cornering lights, tyre pressure monitoring, and an emergency call button.

The only safety item which can feel intrusive when driving is the adaptive cruise control as it has a feature that scans for bends in the road and will slow the car down in anticipation of them. On paper, this isn’t a bad thing but in practice, it was sporadic when it activated and sometimes slowed the car dramatically on bends you wouldn’t even call bends!

AEB with car, pedestrian, cyclist, motorcyclist, backover and intersection turning assist is standard and operates from 5.0 - 80km/h (up to 180km/h for car detection).

There are two ISOFIX child seat mounts and three top-tether anchor points in the rear row. The seat isn't wide enough to accommodate three child seats side by side, so two will fit best.

The Cadillac Optiq is covered by the brand's five-year, unlimited-kilometre warranty, which lags the similarly sized and priced Hyundai Ioniq 9 and Kia EV9, but is on par with the Germans. There's also five years of roadside assistance, while the battery is co vered for eight years or 160,000km. 

Service intervals are 12,000km or 12 months, and the brand says it is still finalising service pricing, so that’s something to ask about before you commit.

Rather than conventional dealers, Cadillacs are typically sold online with hands-on inspection at 'Experience Centres' - currently one in Sydney and one Melbourne. Service and test drive sites are also in place in Brisbane, Canberra, Adelaide, Perth and Hobart.

The NX is offered with a five-year/unlimited-kilometre warranty, which is on par with its European rivals.

It comes with a five-year capped price servicing program, where services are competitively priced at $595 each.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
