Lexus RX 350h Executive cost to own in Singapore — the true 5-year total
As of August 6, 2026, the Lexus RX 350h Executive costs S$456,800 on the road (price with COE). Over 5 years, owning one (hybrid) costs about S$279,434 in Singapore — S$4,657/month, S$3.19/km — where COE and ARF, not petrol, dominate. That's S$48,680 more than a comparable BMW i5 eDrive40 over the same 5 years.
COE is set by a biweekly auction and swings thousands of dollars — every figure here uses the S$124,790 (Cat A) / S$126,236 (Cat B) COE assumption. Confirm the current COE before you commit; it is the single biggest line in the price. Source: LTA registration-cost sheet, 2026-08-06.

Where the money really goes — COE + ARF dwarf the fuel
The registered price with COE for the Lexus RX 350h Executive is S$456,800. COE + ARF alone are S$234,251 of that — many multiples of the electricity or petrol you'll ever buy. That is the honest story of Singapore car cost.

How depreciation works here: it is the registered "price with COE" minus what you get back at de-registration — the unused COE (rebatable over the 10-year licence), the PARF rebate (a capped % of ARF paid), and the car's remaining market value. Where a published Singapore depreciation figure exists (PaperValue / sgCarMart), we use it — the straight-line S$/yr buyers actually quote. That is why the S$100k+ upfront, not electricity or petrol, dominates the 5-year total. What you'd get back at deregistration (official PARF + COE rebate) →

- On cost per month the Lexus RX 350h Executive ranks #12 of 12 SUV models we price in Singapore.
What the Singapore stack does to the Lexus RX 350h Executive specifically
The Lexus RX 350h Executive declares an OMV of S$65,806 — the import value every Singapore tax on it is computed from. That produces S$100,515 of gross ARF before any adjustment. Its VES band C1 adds a S$7,500 surcharge on top of it (120–159 g/km → S$7,500 surcharge). It registers in COE category B, so this page prices it at the S$126,236 Cat B assumption — 28% of its S$456,800 registered price on its own, and COE plus ARF together are 51% of it. For scale, the COE alone is about 7× everything the Lexus RX 350h Executive will spend on petrol in 5 years (S$19,152).
The Singapore market quotes depreciation on this car at S$39,700/yr (sgCarMart new-car info carcode 21653, subModel id 9119 "2.5 Executive": depreciation S$39,700/yr, price S$446,800 (COE-inclusive), priceFluctuation date 2025-11-20 (current 5th-gen RX; sibling id 9109 "2.5 Luxury" dep S$41,900 cross-confirms the trim split).

Basis S$446,800 sits ~2.2% below today's Lexus SG list S$456,800, so the figure is marginally conservative; PARF rebate is cap-bound at S$30,000 (ARF S$100,515), already reflected in the published depreciation. OMV S$65,806 and CO2 144 g/km (VES C1, +S$7,500 surcharge) from LTA M032 "Cars Registered in May 2026" row 186; retail S$456,800 COE-inclusive (non-guaranteed basis) from official Lexus SG (lexus.com.sg RX 350h, entry grade 2.5 Executive), fetched 2026-07-02.) — that published figure, not a residual curve of ours, is what drives the 5-year total above. Road tax on the Lexus RX 350h Executive is assessed on engine capacity — 2,487 cc; an EV instead pays a power-based rate plus a flat S$700/yr component in lieu of fuel duty.
