The Renault Symbioz E-Tech full hybrid stands out for boot flexibility: its sliding rear bench lets Renault quote 492 litres with the bench back and 624 litres with it forward. The Toyota Corolla Cross has a similar exterior footprint, but its boot and official fuel-use figures depend on the engine and trim. The published numbers below are European examples from different model-year sources, not a like-for-like test or a verdict on every local version.

Which hybrid SUV has the bigger boot?
The Symbioz has the more flexible published boot figures. Renault UK lists 492 litres with the full-hybrid rear bench in its rear position, 624 litres with it slid forward, and 1,582 litres with the seats folded. Renault’s page includes a VDA-equivalent note, so the figures should be understood in the stated configurations and convention rather than treated as a universal, directly measured win.
Toyota Europe’s 2025 product guide lists maximum boot capacities of 473 litres for the 1.8 HEV FWD and 425 litres for the 2.0 HEV FWD. Those are engine-specific figures; they are not a like-for-like comparison with every Symbioz bench position. If boot space matters, check the exact variant and how the manufacturer states the capacity, then test your usual luggage in the vehicle.

Does the Symbioz rear bench slide?
Yes. The sliding rear bench is the key flexibility feature behind the Symbioz’s different boot figures: move it back for more space for rear passengers or forward to increase luggage room. The quoted 492- and 624-litre capacities refer to those two bench positions; the 1,582-litre figure is with the rear seats folded.
The published dimensions alone do not establish which vehicle gives more usable rear-seat room. The models have nearly the same wheelbase, but that does not account for seat shape, cabin layout, or the effect of a slid-forward bench on passenger comfort. If you regularly carry adults or child seats, assess the actual seating position and access in the trim you intend to buy.

Is the Renault Symbioz more economical than the Toyota Corolla Cross?
On the cited official combined figures, the launch-era Symbioz E-Tech full hybrid 145 is rated at 4.7 L/100 km WLTP. Toyota Europe’s 2025 guide gives the Corolla Cross 1.8 HEV FWD 4.9–5.0 L/100 km and the 2.0 HEV FWD 5.2 L/100 km. Renault’s launch release also lists 105 g/km CO2 for that Symbioz powertrain.

These figures suggest a small published advantage for the cited Renault configuration, but they are not results from a shared road test. WLTP ratings are homologated values, not a promise of what a particular driver will achieve. Model year, trim, wheels, drivetrain, and local homologation can affect the applicable figure. Compare the official combined rating for the exact versions sold in your country, and keep it separate from observed consumption.

How much bigger is the Toyota Corolla Cross?
In Toyota Europe’s 2025 guide, the Corolla Cross is 4,460 mm long with the 1.8 HEV FWD and 4,465 mm with the 2.0 HEV FWD. Renault UK lists the Symbioz at 4,413 mm. That makes the Toyota 47–52 mm longer in these examples. Its listed body width is 1,825 mm against 1,797 mm for the Renault, while wheelbases are almost the same: 2,640 mm and 2,638 mm respectively. Width figures exclude mirrors.
The difference in overall length is modest and does not, by itself, prove which vehicle is easier to park or roomier inside. Check turning and parking needs, visibility, and the exact dimensions of the local version if those are decisive for you.

Do the model year and local specification matter?
Yes. The figures come from different sources and periods: Renault’s fuel-use number is for its launch-era E-Tech full hybrid 145, while Toyota’s are from a 2025 European product guide. Renault’s UK dimensions page supplies the Symbioz size and boot capacities, and Toyota’s cited guide distinguishes Corolla Cross engines. These examples should not be read as a guarantee that every current local trim has those specifications.

Which one costs less to own?
The available figures do not support a reliable overall ownership-cost winner. Purchase prices, incentives, finance rates, warranties, servicing, insurance, depreciation, and repair costs vary by country, date, and vehicle specification; there is no matched current comparison for these two models here.
For a useful local comparison, gather the same inputs for equivalent trims and powertrains:
- Current drive-away price, discounts, incentives, and finance terms.
- Warranty coverage and scheduled service prices over the period you expect to keep the car.
- Insurance quotes for your circumstances and location.
- Your annual distance and local petrol price, using the exact local fuel-consumption ratings as estimates rather than real-world guarantees.
- Evidence for resale values and likely repair costs over your planned ownership period.
Without those inputs, neither the small difference in the cited WLTP ratings nor a manufacturer’s reputation establishes which will cost less for you to own.
