smart #5 vs Zeekr 7X: EV Comparison in Singapore

The smart #5 and the Zeekr 7X RWD Long Range are two of the most cross-shopped Chinese-brand flagship electric SUVs (battery electric vehicle / BEV) in Singapore, and they share more under the skin than the showroom badges suggest. Both are Geely Group cars, both run an 800V architecture, and both carry a 100 kWh NMC battery. That puts them in the fastest-charging tier currently available in the SG market, well ahead of the more common 400V flagships from other brands. The two cars then split on brand finish, body format, and DC-curve tuning. The smart #5 is the Mercedes-Geely joint venture's flagship SUV, with the Stuttgart-tuned interior, the smart brand polish, and the five-seat SUV body. The Zeekr 7X RWD Long Range is Zeekr's own flagship on the same group platform, tuned in-house with an explicitly faster DC peak on the EV-Database measurement, a slightly longer claimed WLTP range, and a 7-seater family-practical body. Both charge on CCS2 across the Singapore public DC network. The decision is about brand character, cabin format, and how much the marginal DC peak gap actually matters to you. This guide weighs the two qualitatively. The exact figures (cost, time, realistic range) are on this site's comparison tool and per-car pages.

Geely Group siblings, two brand identities

The smart #5 and the Zeekr 7X RWD Long Range are siblings in the Geely Group BEV lineup, and that lineage matters more than the rebadge framing usually suggests. Both cars are flagship Chinese-brand electric SUVs aimed at the Singapore buyer who wants the most modern 800V architecture and a 100 kWh NMC pack, in a body large enough for family use. They share the underlying Geely SEA platform DNA, the same battery chemistry, the same 800V architecture, and the same CCS2 charge port standard. From there the brand identities diverge sharply. The smart #5 is the result of the Mercedes-Benz and Geely joint venture: smart is now a JV brand, with the cabin design, the interior trim, the soft-touch surface choices, and the brand polish executed under Mercedes-Benz oversight. The Zeekr 7X is the in-house tuning of the same group platform under Zeekr's premium-tier brand, with cabin choices and exterior styling executed by Zeekr's own Gothenburg-led design team.

The body format follows the brand split. The smart #5 is a five-seat SUV: cleaner footprint, easier to park in dense SG carparks, and the brand polish that comes with the Mercedes JV. The Zeekr 7X RWD Long Range is offered as a 7-seater configuration with a third row for family use, which is rare in the 800V flagship tier and is a meaningful differentiator if you actually need the extra row. Both are pure BEVs, not hybrids, so each charges at home on a Level 2 AC wallbox or at a public DC fast charger on weekends and trips. For Singapore buyers cross-shopping at this end of the Chinese-brand market, the platform sharing means the underlying engineering risk is the same; the choice is genuinely about brand character and body format, not about which platform is more mature.

Charging speed and 800V architecture

Both cars sit at the fastest-charging tier currently available in Singapore: 800V architecture (rather than the 400V used by most of the older flagship competition) and a 100 kWh NMC pack. On DC fast charging the smart #5 has an extremely fast peak power figure on the spec sheet and posts a very quick measured 10 to 80% session time on EV-Database. The Zeekr 7X RWD Long Range goes a step further on the measured curve: its DC peak measured on EV-Database meaningfully EXCEEDS its rated peak on the brochure, which is the unusual case where the in-the-wild measurement is faster than the manufacturer claim. The Zeekr therefore posts the SHORTER measured 10 to 80% time of the pair. Both times are short enough that a coffee-stop session on the Singapore public network is realistic on either car, but the Zeekr keeps a measurable edge for buyers who fast-charge often.

The wider Singapore network supports both cars equally. Both use CCS2 across SP Mobility, Shell Recharge, ChargeNow, BlueSG, and the other CPOs deployed across the city, with no proprietary network involvement on either side. The practical caveat is that the 800V advantage is fully realised only on 800V-capable public DC stations: where the available DC charger is older 400V hardware, the 800V architecture is throttled to the charger's limit, and the gap between the two cars narrows. Home charging is similar on either car. For dense SG geography where most days are well under 100 km of driving, the home-charge story is what most owners actually live with day to day. The 800V DC peak advantage is the occasional convenience for long weekend drives or cross-border trips up to Malaysia.

Range, cabin polish, and family practicality

On claimed WLTP range the Zeekr 7X RWD Long Range carries a SLIGHTLY LONGER brochure figure than the smart #5, helped by Zeekr's own efficiency tuning on the same 100 kWh pack and the specific aero choices on the 7X body. The gap is modest rather than dramatic. The smart #5 counters with the lighter five-seat body and a tighter footprint that pays off in dense Singapore traffic and urban speeds, where rolling resistance and air-conditioning load dominate. Both are WLTP-rated in Singapore, so the brochure comparison is apples-to-apples in principle.

Cabin character is where the brand identities pull hardest. The smart #5 leans on the Mercedes-Benz oversight from the JV, with the smarter interior trim, the more deliberate soft-touch material choices, and the tuned NVH that the Mercedes side of the partnership is known for. The Zeekr 7X leans on Zeekr's premium positioning in the Chinese flagship segment, with a heavily-equipped tech stack, the bespoke premium feel, and the third row of seats that the smart #5 simply does not offer. Realistic range on Singapore roads (dense traffic, frequent air-conditioning use, urban speeds) drops below either brochure figure, but the gap between the cars remains modest. To judge real 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?

The choice in Singapore comes down to brand finish, body format, and how much the marginal DC peak gap actually matters at your typical Singapore fast charger. Pick the smart #5 if you value the Mercedes-Geely JV brand polish, the Stuttgart-tuned interior trim, the cleaner five-seat SUV footprint that parks easier in dense SG carparks, and an already extremely fast 800V charging curve that handles a long weekend trip comfortably. Pick the Zeekr 7X RWD Long Range if you prioritise the higher measured DC peak on the EV-Database charge curve, the slightly longer claimed WLTP range, the 7-seater third-row body for family use, and Zeekr's own in-house premium brand identity on the same Geely Group platform.

To close the decision with real numbers, this site provides a comparison tool prefilled with the smart #5 and the Zeekr 7X RWD Long Range side by side, a per-car page for each, and a charging cost calculator that works it out with your own electricity tariff and battery percentage.

Frequently asked questions

Which charges faster in Singapore, the smart #5 or the Zeekr 7X?

Both cars sit at the fastest-charging tier currently available in Singapore: 800V architecture and a 100 kWh NMC pack. The smart #5 posts an extremely fast measured 10 to 80% time on EV-Database. The Zeekr 7X RWD Long Range goes a step further: its measured DC peak on the EV-Database curve meaningfully exceeds its rated brochure peak, so it posts the shorter measured 10 to 80% time of the pair. Both are CCS2 cars, so the Singapore public DC network treats them identically: SP Mobility, Shell Recharge, ChargeNow, BlueSG, and the other CPOs all support both. The 800V advantage applies fully only on 800V-capable public DC stations; on older 400V hardware the gap narrows. Exact charging times are on this site's comparison tool.

Which one has more range?

The Zeekr 7X RWD Long Range claims the slightly longer WLTP range than the smart #5 on the brochure, helped by Zeekr's own efficiency tuning on the same 100 kWh NMC pack and the specific aero choices on the 7X body. Both are WLTP-rated in Singapore, so the brochure comparison is apples-to-apples in principle, but the smart #5's lighter five-seat body closes part of the gap at lower urban speeds in dense SG traffic. Realistic range on Singapore roads drops below the brochure figure on both cars; the gap between them remains modest. 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. Both cars carry a 100 kWh NMC pack, so a full charge from empty needs roughly the same total energy on either, and the cost to charge the same span, say 20% to 80%, follows the percentage rather than the brand. Charging at home on the SP Group tariff is far cheaper than public DC fast charging on both cars. Exact side-by-side figures for Singapore are on this site's comparison tool.
