Acura ZDX vs Cadillac Lyriq: Ultium Twin EV Comparison in the United States
The Acura ZDX A-Spec RWD and the Cadillac Lyriq are two midsize luxury electric SUVs (battery electric vehicle / BEV) that look like obvious rivals in the United States, and they are, but with a twist most cross-shops do not have: they are mechanical relatives. Both ride on General Motors' 400V Ultium platform, the ZDX being GM Ultium hardware wearing an Acura badge (a close sibling of the Chevrolet Blazer EV) and the Lyriq being the Cadillac Ultium SUV the platform was effectively built around. Because they share that architecture at the same DC-peak class, fast charging between them is a genuine tie rather than a contest, so the usual headline question of which one refills faster has an honest answer of neither. That changes what this comparison is about. With charging settled, the decision rests on the things that actually separate two relatives wearing different badges: the brand, the cabin design, the driving tune, the price positioning, and the ZDX's slightly larger battery. Both are pure BEVs, both use NMC batteries, and both are EPA-rated with near-identical range. This guide weighs the two qualitatively. The exact figures (cost, time, realistic range) are on this site's comparison tool and per-car pages.

Platform twins wearing different badges
The Acura ZDX A-Spec RWD and the Cadillac Lyriq are unusually close under the skin for two cars from different brands. Both are built on General Motors' 400V Ultium platform, the modular battery-and-drive architecture GM uses across its modern electric lineup. The Lyriq is the Cadillac SUV that platform was effectively shaped around, the brand's volume electric flagship. The ZDX is GM Ultium engineered and sold under an Acura badge, a close relative of the Chevrolet Blazer EV that gives Honda's luxury division a credible midsize electric SUV without building a new platform from scratch. Calling them platform twins is fair: the bones, the battery chemistry, and the charging hardware come from the same family. What differs is everything wrapped around those bones, which is exactly where this comparison lives.
Both cars are pure BEVs, not hybrids, and both can charge at home on a Level 2 AC wallbox or at a public DC fast charger on the road. Both use NMC (nickel manganese cobalt) batteries, so battery-care advice is identical on either: charging routinely to roughly the mid-to-high range and saving a full 100% charge for trips is the gentle habit that keeps a pack healthy. With a shared platform and shared chemistry, the long-term ownership math on charging and battery wear is essentially the same car twice. That shared starting point is what makes the badge, the cabin, the tune, and the price the real decision here rather than the spec sheet.
Charging is a genuine tie, not a contest
Here is the part that separates this comparison from most: DC fast charging between the Acura ZDX A-Spec RWD and the Cadillac Lyriq is a true tie. Both run the same 400V Ultium architecture at the same DC-peak class, so on a public fast charger they behave the same way, draw power the same way, and complete the most-used 10-80% portion of a charging stop in broadly the same time. There is no faster sibling to chase here. Anyone telling you one of these two charges meaningfully quicker than the other is reading a difference that the shared platform does not support. On the road, the practical experience of plugging in and topping up is interchangeable between them.
The one honest spec nuance is battery size. The Acura ZDX carries a marginally larger battery than the Cadillac Lyriq, which means a full charge from empty holds a little more energy and, all else equal, can stretch a little further between stops. But a slightly bigger pack is not a charging-speed advantage; on the same 400V architecture and the same DC-peak class, the ZDX simply has a touch more to fill, not a faster way to fill it. Port standards are converging across the United States as the industry adopts NACS, and since both cars share GM's charging hardware, that transition lands on them identically. So the charging chapter of this comparison closes the way it opened: a wash, with the only real footnote being the ZDX's modestly larger reserve.
Range is near-identical, so badge and cabin decide
Range follows the same pattern as charging. The Acura ZDX A-Spec RWD and the Cadillac Lyriq post near-identical EPA range, close enough that range is not the tiebreaker it usually is between two SUVs in this class. The ZDX's slightly larger battery and the Lyriq's tuning roughly cancel out on the brochure, and both figures are quoted on the EPA cycle, so the comparison is apples-to-apples. Both also return less than the sticker in cold weather with the heater running and the car loaded, as every BEV does. With charging tied and range tied, the spec sheet has run out of separators, and the decision moves entirely to the two cars' personalities.
This is where the badges finally diverge. The Cadillac Lyriq leans into Cadillac's design language and brand heritage, a distinctly American luxury statement with a cabin and presentation built around that identity, often positioned as the more established premium choice. The Acura ZDX takes the same Ultium underpinnings and dresses them in Acura's sportier, more driver-focused character, with the A-Spec trim's styling cues and a tune aimed at a slightly more engaged feel, frequently arriving with a sharper price of entry. Neither is objectively better; they are two interpretations of the same hardware aimed at different buyers. To judge realistic figures rather than headline numbers, this site presents discounted realistic-range estimates side by side with each car's cost per charge, computed automatically from the official specifications.
Which one suits you?
Pick the Cadillac Lyriq if you want the Cadillac badge and the brand's design identity, you value an established American luxury presence, and the cabin and brand heritage are central to the purchase. It is the Ultium SUV the platform was built around, it charges exactly as quickly as its Acura relative, and its EPA range is essentially the same, so you give up nothing on the fundamentals to get the Cadillac experience. Pick the Acura ZDX A-Spec RWD if you prefer Acura's sportier, more driver-focused character and styling, you want the slightly larger battery and the marginally longer reserve that comes with it, and you like the value angle that often comes with the Acura badge over the Cadillac. The honest truth is that on charging speed there is no winner between them, because they share GM's 400V Ultium platform at the same DC-peak class; the choice is brand, cabin, tune, and price, plus the ZDX's modest battery edge.
Because both use NMC batteries and the same Ultium architecture, charging behaviour and long-term battery care are equal and not a differentiator. To close the decision with real numbers, this site provides a comparison tool prefilled with the Acura ZDX A-Spec RWD and the Cadillac Lyriq side by side, a per-car page for each, and a charging cost calculator that works it out using your own electricity rate and battery percentage.
Frequently asked questions
Which charges faster, the Acura ZDX or the Cadillac Lyriq?
- Neither. This one is a genuine tie. The Acura ZDX A-Spec RWD and the Cadillac Lyriq are platform twins: both ride on General Motors' 400V Ultium architecture at the same DC-peak class, so they accept fast-charging power the same way and complete the most-used 10-80% portion of a charging stop in broadly the same time. There is no faster sibling to pick here, and any claim that one charges meaningfully quicker than the other is not supported by the shared platform. The only spec nuance is that the ZDX carries a slightly larger battery, which adds a touch more energy to fill rather than a faster way to fill it. So the decision should rest on badge, cabin, tune, and price, not on charging. Exact charging times for the United States are on this site's comparison tool.
Are the Acura ZDX and Cadillac Lyriq really the same car?
- Not the same car, but close relatives. Both are built on General Motors' 400V Ultium platform and share the battery chemistry and charging hardware that comes with it. The Cadillac Lyriq is the Cadillac SUV the platform was effectively built around, while the Acura ZDX is GM Ultium engineered and sold under an Acura badge, a close sibling of the Chevrolet Blazer EV. Think of them as platform twins wearing different badges: shared bones, different brand, cabin, styling, and tune. That is exactly why charging and battery care are identical between them and the decision comes down to the things each brand wraps around the shared hardware.
Which has more range, the Acura ZDX or the Cadillac Lyriq?
- In practical terms it is a tie. The Acura ZDX A-Spec RWD and the Cadillac Lyriq post near-identical EPA range, close enough that range is not the deciding factor it often is between SUVs in this class. The ZDX carries a slightly larger battery, but the two cars' figures land essentially on top of each other on the brochure once tuning is accounted for. Both numbers are EPA-rated, so the comparison is apples-to-apples, and both return less in cold weather with a full load aboard. Side-by-side realistic-range estimates are on this site's comparison tool.
Which is cheaper to charge?
- Charging cost depends mainly on battery capacity and the electricity rate you use, not on the brand. Because the Acura ZDX A-Spec RWD carries the slightly larger battery, a full charge from empty needs a touch more total energy than the Cadillac Lyriq, although the cost to charge the same span, say 20% to 80%, follows the percentage rather than the battery size, so it is very close between them. Charging at home on a Level 2 AC wallbox is far cheaper than public DC fast charging on either SUV, and since both share GM's 400V Ultium platform their charging behaviour is the same. Exact side-by-side figures for the United States are on this site's comparison tool, and the charging cost calculator works out the cost from your own electricity rate.
