The Formentor petrol boot is 450 litres - workable for most buyers. The PHEV boot drops to 345 litres to accommodate the battery. Motor Source customers comparing the Formentor and the Tiguan side-by-side consistently describe the boot difference as the moment that determines the decision - the Tiguan's scale swallows what the Formentor simply cannot.

For solo commuters, couples and buyers who do not regularly fill their boot, 345-450 litres is entirely adequate. For families who routinely load for weekly shops, holidays or sports activities, the Formentor PHEV's reduced boot is a daily compromise rather than a minor inconvenience. Buyers should load both boots with their real items before deciding.

The Tiguan delivers a 652-litre boot - larger than the Kia Sportage, larger than the Honda CR-V and a full 307 litres more than the Formentor PHEV. The rear seats slide, recline and fold completely flat from the boot using remote levers. Motor Source customers who buy the Tiguan for family use describe the boot as one of the most appreciated qualities in daily ownership - it simply accommodates what a family needs to carry without negotiation.

Three adults sit comfortably abreast in the rear with genuine knee and headroom. The commanding driving position, wide rear door openings and flexible seating system make the Tiguan the more capable family transport of the two cars by a significant practical margin.

The Formentor V1 petrol at £28,468 is £2,964 less than the Tiguan Life petrol at £31,432 - and that gap is significant at this price point. The Formentor eHybrid PHEV at £31,010 is £4,158 less than the Tiguan eHybrid at £35,168. Both comparisons show the Formentor delivering more affordable entry to a sporty, well-equipped SUV.

The Motor Source savings are also notably large on both Formentor variants - £6,847 off the petrol and £11,000 off the eHybrid. Motor Source customers who are price-conscious and compare both cars frequently describe the Formentor's value position as the strongest argument in its favour once the Tiguan's larger size is acknowledged as something they simply do not need.

The Tiguan commands a premium over the Formentor at every comparable specification. The £31,432 petrol entry and £35,168 eHybrid represent prices that reflect the Tiguan's larger size, longer list of standard equipment and stronger residual value position. Motor Source customers who choose the Tiguan despite the higher price consistently describe the practical scale as justifying the premium - you are buying a larger, more capable vehicle.

The Tiguan also holds its value well on the used market - the VW badge and SUV body style combine to maintain strong residuals that partially offset the higher purchase price over a three-year ownership cycle. For buyers who finance on PCP, the Tiguan's stronger residual value affects the monthly payment calculation in a way that is worth confirming at the point of quotation.

The Formentor eHybrid claims 70+ miles and Motor Source customers who charge regularly report 55-60 real-world miles in mixed conditions. At £31,010 through Motor Source it is £4,158 less than the Tiguan eHybrid at £35,168. For company car drivers where the BIK rate is the primary financial filter, both cars qualify for low BIK bands - the Formentor's advantage is its lower P11D value, which compounds the lower BIK rate into a lower absolute annual tax bill.

Motor Source customers who specify the Formentor eHybrid as a company car consistently describe the combination of engaging driving character, low BIK and substantial Motor Source saving as the clearest value proposition available in the sporty compact PHEV SUV segment.

The Tiguan eHybrid claims up to 75 miles WLTP - among the longest PHEV ranges in the family SUV class and nearly double the Hyundai Tucson PHEV's 43.5 miles. It also supports rapid charging, allowing for faster top-ups at public chargers than many PHEV rivals. At £35,168 it is substantially more expensive than the Formentor eHybrid, but it also delivers a significantly larger car with a full-size family boot.

For company car drivers who also need to carry a family regularly and want the longest PHEV range in the SUV segment, the Tiguan eHybrid is the stronger all-round proposition despite the higher P11D value. The BIK saving versus a conventional petrol or diesel SUV is very large at 75-mile range; the higher purchase price is partially recovered through company car tax efficiency over a three-year contract.

The Formentor drives like a hot hatch in SUV proportions - low seating position, direct steering, flat cornering and a firm, sporty suspension that makes it feel genuinely different from any high-riding family SUV. Motor Source customers who test the Formentor back-to-back with the Tiguan describe the driving experience gap as immediate and substantial - the Formentor feels alive where the Tiguan feels composed.

The top-spec Formentor with four-wheel drive provides grip that defies the car's proportions. Even the entry V1 trim has a sporty edge with direct steering and well-judged suspension. Motor Source customers who buy the Formentor as a driver's car are consistently satisfied with the dynamics - no comparable-priced compact SUV matches it for engagement.

The Tiguan is a comfortable, refined and competent family SUV - not an engaging driver's car. Its ride quality is well-judged for daily use, soaking up speed bumps and road imperfections with the kind of settled composure that makes a 200-mile family trip less tiring than a Formentor at the same pace. The high commanding seating position and light steering make it easy and unstressful in town and on motorways.

Motor Source customers who buy the Tiguan are not seeking a hot hatch experience - they are buying refined family transport. The Tiguan delivers exactly that. For buyers who cover significant weekly motorway mileage with passengers on board, the Tiguan's settled, quiet character is a daily quality-of-life advantage over the Formentor's firmer, noisier motorway persona.

The Cupra Formentor carries a five-year, 90,000-mile warranty - significantly more generous than Volkswagen's own three-year package on the Tiguan. This is a structural financial protection difference that Motor Source customers considering both cars consistently cite when the reliability question is raised. Cupra's lower Driver Power ranking (28th of 31) makes the longer warranty more rather than less important as an ownership safeguard.

For buyers who plan to own for five years or more, the Formentor's warranty covers a full five years regardless of annual mileage up to 90,000 miles total. Combined with the lower purchase price, this makes the Formentor the more financially protected ownership proposition over a long cycle - even accounting for its lower reliability survey position.

The VW Tiguan carries a standard three-year, 60,000-mile warranty - the shortest and most mileage-restricted in this comparison. Motor Source customers who have researched the Tiguan thoroughly are often surprised by the contrast with the Formentor's five-year cover. Given that some Motor Source Tiguan customers have reported reliability concerns including turbo failures, transmission issues and software problems, the three-year warranty leaves buyers exposed after year three.

The community advice for Tiguan buyers is consistent: consider an extended warranty as a safeguard, particularly given the reported complexity of software and hybrid system issues in early 2026 production. Motor Source strongly recommends confirming extended warranty options at point of purchase for any Tiguan buyer who plans to own beyond three years.

The Formentor's distinctive copper trim, LED ambient lighting arc and dark, moody "nightclub" character make it feel premium and unlike any other VW Group interior. Physical steering wheel buttons are standard. The 12.9-inch touchscreen is clear, responsive and fast. Motor Source customers who sit in both the Formentor and the Tiguan on the same day consistently note the Formentor's stronger interior personality and the sense of visual occasion it creates.

The honest limitation: touch-sensitive sliders under the main screen for volume and temperature can be frustrating to operate on the move without looking. Safety feature menus are buried in less obvious places in the infotainment. These are shared VW Group interface compromises that the Tiguan's physical steering wheel buttons partially address, though both cars now feature physical wheel controls as standard.

The Tiguan interior is described as "a cut above" many SUVs at its price - soft-touch plastics throughout, Alcantara trim on R-Line spec, felt-lined door bins that prevent rattles and a damped glovebox. The same 12.9-inch touchscreen as the Formentor is standard on every model with smartphone-style home screens and configurable shortcuts. Physical steering wheel buttons were reintroduced in the current generation in direct response to customer feedback.

Motor Source customers who buy the Tiguan describe the interior quality as the feature that most exceeds expectation - it feels genuinely premium rather than mainstream at a price point where many rivals feel merely adequate. The overall size and space of the interior also contributes to this premium feeling - a higher roof, wider cabin and longer body give it an airy quality the Formentor's lower, coupe-SUV profile cannot replicate.

Cupra ranked 28th out of 31 manufacturers in the most recent Driver Power survey - a clear and factual limitation that Motor Source customers who research thoroughly consistently raise. The five-year, 90,000-mile warranty is the brand's primary structural response to this concern and provides meaningful protection during the highest-risk ownership window. Motor Source customers who buy the Formentor with awareness of the reliability ranking describe the warranty as the reassurance that makes the purchase defensible.

The Tiguan carries well-documented reliability concerns from Motor Source customers. Turbocharger failures on 2026 models, transmission issues, excessive oil consumption and software malfunctions including "Travel Assist Not Available" errors have all been reported. Extended repair wait times of weeks to months at dealers are a specific community concern. The three-year, 60,000-mile warranty provides limited cover for buyers who encounter these issues after year three.

Hybrid charging inconsistencies have also been noted on 2025/26 eHybrid models - the car charging significantly slower than expected is a frustrating ownership experience when the PHEV range is part of the financial justification. Motor Source strongly recommends Tiguan buyers investigate extended warranty options at point of purchase to protect beyond the standard three-year cover.

The Formentor's five-star Euro NCAP rating includes a 93% adult occupant protection score - exceptional within the five-star band. Entry V1 trim includes adaptive cruise control, all-round LEDs, wireless phone charging, a digital dashboard, the 12.9-inch touchscreen and wireless Apple CarPlay and Android Auto as standard. Higher trims add an assisted motorway driving system and adjustable suspension dampers.

The Tiguan also holds a five-star Euro NCAP rating. Entry Life trim includes front and rear parking sensors, a reversing camera, adaptive cruise control, autonomous emergency braking and the 12.9-inch touchscreen as standard. Physical steering wheel buttons are reintroduced on the current generation. The high seating position provides good all-round visibility in urban environments. R-Line and higher trims add a panoramic sunroof and further driver assistance technology.

The Formentor is one of the most visually distinctive compact SUVs available at any price. Its low-slung coupe profile, aggressive front end and copper badge detailing make it immediately identifiable in a sea of conventional upright SUVs. Motor Source customers who buy it frequently mention that it attracts attention and generates conversation in a way no mainstream VW Group product does. It is a car that communicates something about its owner's priorities.

The copper accent debate is real in the buyer community - some love it, others describe it as dated. Cupra is phasing in more subtle versions. The fundamental shape and proportion, however, remain more dynamic than the Tiguan at every trim level. Most Formentors on UK roads appear in dark or neutral colours; buyers who want the car to stand out further have a wide palette available.

The Tiguan is a handsome, assured family SUV - it does not try to polarise opinion and succeeds in looking premium without being aggressive. The current generation is a significant styling step forward from the previous model, with sharper lines and a more confident front end. R-Line trim adds a sportier exterior package including body-colour bumpers and larger alloys that brings it closer to the Formentor visually without changing its fundamental character.

Motor Source customers who choose the Tiguan over the Formentor on style grounds are typically buyers who want to look successful rather than sporty - the Tiguan communicates premium family transport in a way that is broadly attractive to most observers. It will not start as many conversations as the Formentor but it will satisfy more buyers who want to age gracefully across a five-year ownership period.

The Formentor occupies the compact coupe-SUV segment - roughly equivalent in footprint to the Hyundai Tucson or SEAT Ateca. It is lower, sleeker and more tightly packaged than the Tiguan. The buyer the Formentor is genuinely right for is someone who wants a sporty, stylish, efficient SUV and does not need the maximum family transport capacity. At £28,468 petrol and £31,010 eHybrid, it is also the more accessible entry point in this comparison.

Motor Source customers who buy the Formentor over the Tiguan because it is cheaper but then discover they needed the Tiguan's space consistently describe post-purchase regret. The right buyer for the Formentor knows they are prioritising driving character, price efficiency and style over maximum practical capacity.

The Tiguan is a full-size family SUV. At £31,432 petrol and £35,168 eHybrid it is priced as one, built as one and serves that brief better than almost any comparable-priced alternative. The buyer the Tiguan is genuinely right for is someone who needs the maximum practical capability from a premium-feeling SUV - family transport, regular full-boot loading, adult rear passengers on long trips - and wants a refined, settled driving experience while doing all of that.

Motor Source customers who buy the Tiguan for its practical scale and use that scale on every trip describe it as exactly the right car. The honest caveat is the three-year warranty and documented reliability concerns - both of which Motor Source advises addressing with extended cover at purchase. The Tiguan is an excellent family SUV. It is not a car to buy without protecting the investment adequately.

Load both boots with the items you actually carry. Put the same items in the Formentor PHEV (345L) and the Tiguan petrol (652L) in the dealer car park. The difference is immediately visible. If the Tiguan carries what the Formentor cannot, the practical decision is made - regardless of how either car drives.

Drive the Formentor on a section of twisty road and note the low driving position, flat cornering and directness. Then drive the Tiguan on the same road. The character difference is immediate - the Formentor feels alive, the Tiguan feels settled. Both are legitimate feelings; assess which one you want to experience on every drive for the next five years.

Drive both at motorway speed for at least 10 minutes. The Formentor's wide-tyre road noise at 70mph and the Tiguan's more settled, quieter character are both felt immediately. For buyers who cover significant weekly motorway mileage, the refinement gap is a daily quality-of-life consideration worth weighting appropriately.

Ask both dealers about extended warranty options. For the Formentor, confirm the standard five-year terms. For the Tiguan, confirm what extended warranty products are available beyond the standard three-year cover and at what cost - then factor that cost into your total ownership budget before comparing prices.

Sit three adults in the rear of both cars. The Tiguan comfortably accommodates three abreast with genuine knee and headroom. The Formentor is more limited across three in the rear. If you regularly carry three rear passengers, this test is definitive.

If you are considering the PHEV variant of either car, drive both with a full charge and note the electric experience. The Tiguan eHybrid claims 75 miles WLTP; the Formentor eHybrid claims 70+ miles with 55-60 miles real-world. For commutes of 30-50 miles each way, this difference is material.

Before leaving the Tiguan dealer, ask yourself honestly: if the Tiguan had the same warranty as the Formentor, would the decision be easier? If yes, factor the cost of Tiguan extended warranty into your budget and compare. The total cost of confident Tiguan ownership is the relevant comparison, not just the purchase price.

Formentor V1 petrol £28,468 (save £6,847 on £35,315 RRP) vs Tiguan Life petrol £31,432 (save £7,488 on £38,920 RRP) - gap of £2,964. Formentor eHybrid V1 £31,010 (save £11,000 on £42,010 RRP) vs Tiguan eHybrid Life £35,168 (save £7,707 on £42,875 RRP) - gap of £4,158. The Formentor Motor Source savings are larger in absolute terms on the PHEV, making the value case particularly strong for eHybrid buyers.

Both PHEV variants qualify for low BIK rates. The Formentor eHybrid at £31,010 has a lower P11D value than the Tiguan eHybrid at £35,168, meaning a lower absolute BIK tax bill even at the same BIK percentage rate. For company car drivers, the £4,158 price gap compounds significantly over a three-year contract when both the lower P11D and lower monthly finance cost are factored in alongside the BIK saving versus conventional alternatives.

Formentor: 5 years / 90,000 miles standard - no additional cost. Tiguan: 3 years / 60,000 miles standard. Extended warranty for the Tiguan is available but adds cost. Motor Source strongly recommends Tiguan buyers factor extended warranty into their budget. For buyers keeping either car for five years, the Formentor's standard warranty cover provides structural protection that Tiguan buyers must purchase separately at additional cost - narrowing the price gap and in some cases reversing it.
