Cadillac Optiq vs Volkswagen ID. Buzz

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 only way to make this car cooler would be to add a split fold-out windscreen and a tube steel luggage rack on the roof.

It’s fast, super practical, comfortable and guaranteed to put a smile on the face of premium family buyers ready to go for something different. And that smile will extend to just about everyone who lays eyes on it. I love it.

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 ID.Buzz GTX is characterised by a unique front bumper with new integrated daytime running lights near its outer edges and a narrower black honeycomb grille. 

GTX badging and the exterior mirror housings are finished in high-gloss black, and 21-inch alloy wheels are standard.

The rich ‘Cherry Red’ solid paint finish of the launch test car is exclusive to the GTX and it’s a fair bet many buyers will stump up the extra $4K required for a two-tone treatment, in this case with ‘Mono Silver’ as the highlight colour.

The interior is familiar ID.Buzz territory, with the long, broad dashtop pushing the windscreen and small front windows beside it into a quintessentially Kombi ‘bay window’-style design.

A 12-inch central multimedia screen sits proud of the multi-layered dash, and a slick 5.3-inch LCD instrument and car data display is fixed in front of the driver.

A black headliner dials up the sporty feel, the electric front seats are a GTX-specific design and the synthetic diamond pattern microfleece trim is highlighted by red contrast stitching and piping. 

The red cross-stitching extends to the steering wheel and smile-inducing stainless steel ‘play’ and ‘pause’ symbols on the accelerator and brake pedals are retained.

The sub-zero cool exterior design manages to merge with a more restrained and practical interior perfectly. VW has solid retro form with the ‘New Beetle’ from the 1990s and this primo ID.Buzz looks amazing. It drew an instant crowd of curious onlookers every time we stopped. 

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 ID.Buzz GTX is offered in shorter wheelbase variants with five- and six-seat configurations for other markets, but here it’s seven seats and long-wheelbase only.

At close to five metres long and just under two metres wide, it’s road-trip ready with heaps of breathing room for all seven occupants.

Placement of the gearshift on the right-hand side of the steering column frees up extra space in the front and there’s heaps of storage including a moveable (and removable) centre console unit between the front seats with pull-out drawers at either end, two trays in each door (the lower one offering room for multiple large bottles), a decent glove box and a fold-out dual cupholder unit.

There’s also an oddments shelf in front of the passenger, a wireless device charging slot in the dash and adjustable fold-down armrests on both sides of the front seats.

Pull the handle on the power-opening sliding side doors and the second row opens up with three seating positions offering hectares of room in all directions. 

This row can be moved 200mm longitudinally if a turf war erupts with those in the third row. And storage is great with two pockets and a fold out table on each front seatback as well as huge door bins with waste baskets included. There are also adjustable vents with temperature control in the roof.

There’s enough head and legroom for adults in the third row although the backrest is relatively upright. Even access is straightforward and there are numerous storage trays, cupholders, air vents and storage slots back there.

Power across the cabin runs to two USB-C ports in the dash, another in the front passenger area and four USB-C charging sockets in the rear.

Boot space increases from a handy 306 litres with all seats up to 1340 litres with the 50/50 split-folding third row down, and 2469L with it and the 60/40 split second row lowered. That’s plenty.

And that 1.6-tonne braked trailer towing capacity means a jet ski, even a mid-size camper trailer, is within hauling range.

The power tailgate is welcome and the rear of the boot’s load platform sits above two storage boxes. But you won’t find a spare of any description back there; a repair-inflator kit is your only option. So beware, a flat could really suck the air out of this mobile family room.

The new ID.Buzz GTX 4Motion is priced at $109,990, before on-road costs, which puts it in the same price zone as a diverse range of large, primo people haulers.

On price, it competes with three-row EVs like the Kia EV9, LDV Mifa 9, and if you stretch the price equation a little further, the Zeekr 009. But in terms of style and personality, this machine lives in a world of its own.

Maybe its VW California Beach sibling comes closest, however that van’s traditional turbo-diesel powertrain stands in stark contrast to the ID.Buzz’s pure-electric vibe.

Once you’ve crested the $100K mark, it’s fair to expect a healthy list of included features and the ID.Buzz GTX doesn’t disappoint.

Aside from the performance and safety tech we’ll get to shortly, the highlights include adaptive cruise control, auto LED matrix headlights, 13-speaker (plus sub-woofer) Harman Kardon audio with digital radio, wireless Android Auto and Apple CarPlay, three-zone climate control, a panoramic (dimmable) glass roof, 30-colour ambient lighting, power-adjustable heated front seats, heated (outer) rear seats and 21-inch alloy rims. 

There’s also a head-up display, a heated steering wheel, rain-sensing wipers, microfleece seat trim, keyless entry and start, electric side doors and tailgate (the latter with hands-free functionality), ‘Ask IDA’ voice control and dark tinted windows.

That’s a strong, class-competitive value equation. Metallic or pearl effect paint will set you back $1890, the two-tone treatment is $4090 and black 21-inch alloys add $380.

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 GTX is a twin-motor AWD, the front unit generating 80kW/134Nm and the rear 210kW/560Nm. Total output is 250kW/590Nm which boosts towing capacity from 1.0-tonne in the single-motor ID.Buzz to 1600kg.

A single-speed transmission sends drive primarily to the rear wheels to maximise efficiency, the dual-motor set-up able to direct power to the front axle as required during acceleration or to manage available traction.

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 ID.Buzz GTX’s 86kWh lithium-ion battery delivers a claimed (WLTP) range of 473km and the car uses a CCS Type 3 socket. VW includes a Mode 2 and Mode 3 cable as standard.

The claimed 10-80 per cent 200kW DC fast charge time is 26 minutes, while the same top-up takes nine hours at a maximum 11.0kW AC capacity.

Claimed energy consumption on the combined (urban/extra-urban) cycle is 20.2kWh/100km (WLTP) and over several hundred kilometres of mainly B-road and freeway running on the launch we saw an average of 24.5kWh/100km, which isn’t out of order given the type of driving involved.

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.

Despite the fact that it weighs in at around 2.8 tonnes (2780kg), Volkswagen Australia says this dual-motor ID.Buzz accelerates from 0-100km/h in 6.4 seconds and on to a 160km/h maximum velocity, if you dare. 

And there is always some serious oomph lurking under your right foot. Trundle along at 65km/h, pin the accelerator, and in roughly two blinks of an eye you’re doing 95km/h. 

Proportionally, this car is like a loaf of bread on wheels - about as high as it is wide. And on the windy launch drive we were buffeted a bit, the car moving sideways slightly when hit with a gust. But overall, it remains stable despite its proportions. That said, some wind noise comes over the bluff nose on the freeway, but never to an alarming degree. 

The ID. Buzz rides on VW’s Modular Electric Drive (MEB) platform and there’s been past criticism of the short-wheelbase versions' ride quality, but there are no such issues here.

Suspension is by struts at the front and semi-trailing arms at the rear and this GTX has had a suspension retune with particular attention paid to key components, including the dampers.

On rural roads that have seen better days, dotted with potholes, bumps and thumps, a combination of that suspension retune and the longer wheelbase helped the GTX handle it well. 

There are five drive modes with Comfort the default. Eco smooths out acceleration, tapers the climate control and reduces overall power, while Sport dials up the powertrain, suspension and steering. Traction optimises the AWD system for loose or slippery surfaces and Individual allows you to cherry pick various attributes for a custom set-up.

Steering is progressive rate and you can feel it loading up nicely as you head into a corner. Not the last word in terms of road feel, but the car points accurately and turn-in is nice and progressive.

At the same time you’ve got the electric motors constantly shuffling drive between the front and rear axles, helping you out if you decide to explore the car’s sporty nature and have a crack in the corners.

Tyres are Hankook Ventus S1 Evo3 EV specials (235/45 fr - 265/40 rr) and in long, sweeping bends, taken at pretty decent speed, they grip hard. Even on coarse-chip B-road surfaces there’s a bit of rumble but it’s far from a roar.

Braking is by large (358mm) ventilated discs in the front and, believe it or not, drums at the back. A well-designed, modern drum brake can work effectively and the regenerative braking in an EV like this is a big factor in terms of washing off speed.

In terms of lower speed manoeuvres, you’ve got a 360-degree camera view as well as a reversing camera and front and rear parking sensors. If you really need some help, Park Assist Plus will get the job done for you.

In terms of ergonomics, we spent hours behind the wheel and the front seats remained comfortable and supportive in terms of lateral grip.

Speaking of grip, the steering wheel is nice to hold. And the cool little 5.3-inch instrument and car data display is clear as a bell, and the large 12-inch media screen is easy to use and working through the different screens is largely intuitive.

The current ID. Buzz range hasn’t been assessed by ANCAP although its sister organisation, Euro NCAP, awarded it a maximum five-star rating in 2022.

As you’d expect, a full suite of driver-assistance tech is onboard including highway-speed AEB with pedestrian and cyclist monitoring, adaptive cruise, lane-keeping assist, lane-change assist, blind-spot monitoring, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring.  

There’s also a 360-degree view and reversing camera, plus Park Distance Control incorporating front and rear proximity sensors.

The airbag count runs to seven - front, front side, curtains covering the second and third rows, as well as a front centre bag. And multi-collision brake minimises the chances of subsequent impacts after an initial crash

There are five top tethers for child restraints; three across the second row and two in the back row, with four ISOFIX anchors across both rows.

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 ID.Buzz GTX is covered by Volkswagen Australia’s five-year/unlimited-km warranty with two years’ roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery.

That general warranty is in line with the mainstream market, although it’s worth noting an increasing number are stepping up to longer terms, including 10 years.  

There’s a 12-year corrosion perforation warranty and keep servicing with an authorised VW dealer and that roadside assistance support will be rolled over for another two years each time.

The recommended maintenance interval is two years/30,000km. Standard scheduled service pricing is $687 for each of the first five workshop visits, while pre-paid plans covering six, eight or 10 years represent savings of between 30 and 35 per cent on that figure, which is pretty handy.
