BMW 4 Series Leasing

Your BMW 4 Series leasing decision

Intelligent Vehicle Finance’s BMW 4 Series leasing route covers petrol Coupe, Convertible and Gran Coupe entries. Choose roof and access needs before engine or equipment, then compare matched contract terms. For a 4 Series electric enquiry, use the separate BMW i4 route. M440i and M4 are different performance propositions.

BMW 4 Series Convertible leasing: roof choice comes first

The Convertible is a purposeful choice when open-air journeys are part of the attraction, rather than an incidental feature on a car selected for its badge. Test how it works with the roof raised as well as lowered. A commuter who uses the car year-round should be comfortable with the normal closed-roof journey, luggage access and parking routine before choosing the most appealing roof-down photograph.

The Coupe makes sense when you prefer a fixed roof and a two-door format. Gran Coupe deserves attention when rear doors and its loading arrangement suit the way the car is shared. We would choose among those bodies before comparing engines. A favourable proposal for the wrong body does not solve a recurring access problem, and more equipment cannot turn a Coupe into a convenient substitute for a car with rear doors.

BMW 4 Series leasing: key facts

• IVF’s September 2026 table lists petrol Coupe, Convertible and Gran Coupe entries under 4 Series.
• The captured engine families are 420i and M440i xDrive, with pack and model-description variations.
• BMW’s current 420i Convertible technical reference has a 184 hp petrol engine and eight-speed automatic transmission.
• BMW describes Convertible luggage capacity as 385 litres with the roof closed and 300 litres with the roof open; verify the supplied specification.
• BMW i4 is the electric Gran Coupe enquiry route on IVF. A mild-hybrid M440i is not a battery-electric i4.
• GOV.UK: the maximum company-car BiK band is 37% in 2026/27 and 39% in 2029/30; the exact car can fall in a lower band.

Compare the BMW 4 Series options

The table compares customer tasks. It is not a specification-equivalence, supply or lease-price comparison.

What IVF lists: 420i, M440i and three body styles

The captured live route has 32 petrol entries across Coupe, Convertible and Gran Coupe. The principal engine descriptions are 420i and M440i xDrive, with M Sport, M Sport Pro and pack variations. Some M440i records include MHT 392 or Black Edition wording while others use different shorthand. Treat those as separate catalogue descriptions until the offered model year and specification are confirmed.

Do not take an output, emissions figure or equipment list from one M440i description and apply it to another merely because the badge matches. Ask for the full production specification, including engine version and options. The current 420i Convertible reference is a 184 hp petrol car with an eight-speed automatic, but that fact does not describe every 4 Series body or an M440i. An M4 enquiry remains a separate performance-model discussion.

For a 4 Series electric search, the relevant IVF route is BMW i4. It has its own battery-electric range and tax assessment. MHT describes mild-hybrid wording in the petrol catalogue, not a charging requirement or a zero-emission car. Choose i4 because an electric Gran Coupe suits the journey and charging routine; do not transfer its figures to this petrol page.

Convertible luggage and everyday access

BMW’s Convertible material distinguishes 385 litres with the roof closed from 300 litres with it open. Those are manufacturer body-reference figures, subject to the supplied car’s specification, not a promise that your bags fit. Try the luggage you use for a weekend away or overnight business trip in both roof states. A successful closed-roof packing exercise can still leave you unable to enjoy the journey as intended.

Check how the car fits the place where it normally parks. Door opening, getting in with a bag and access to the luggage compartment should all form part of the test. For Convertible use, follow the supplied car’s roof-operation guidance and keep any required space clear. Do not decide from a boot-volume number without checking the mechanism and loading arrangement you will actually use.

If rear passengers are common, let them try entry and exit as well as sitting behind the correctly adjusted front seat. For Gran Coupe, compare the opening and load shape with the items you carry, rather than assuming it is simply a Coupe with extra doors. Small differences in the routine can matter more across several years than an optional exterior detail you notice only when approaching the car.

420i or M440i: define what the engine needs to deliver

A 420i enquiry may be primarily about the 4 Series body, comfort and equipment. An M440i enquiry should identify a deliberate preference for that performance powertrain. Compare the actual cars on roads that reflect your use and note their wheel, seat and suspension specifications. The demonstration car and the quoted derivative need to be meaningfully comparable before a driving impression can guide the order.

Obtain insurance terms for the intended body and engine and understand which tyre costs remain yours. A maintenance option should identify inclusions and exclusions clearly, particularly where wheels differ. For a Convertible, ask about the supplied roof’s care requirements and the difference between servicing, warranty and accidental damage. Do not assume that a general maintenance description covers every part of an open-top car.

How a 4 Series lease-price enquiry becomes a usable comparison

Specify Coupe, Convertible or Gran Coupe before asking for a quotation. Then give the engine, must-have equipment, annual mileage and preferred agreement term. Explain whether the mileage is steady commuting or includes long seasonal journeys. IVF can use that brief to compare suitable proposals from its funder panel, subject to the actual vehicle and individual funder criteria.

Keep initial rental, maintenance and fees on the same basis when comparing two proposals. If one is an M440i from a different model description or one changes the body entirely, treat that as a substantive choice. For a business enquiry, show the accountant the P11D and emissions of each actual car. For personal hire, assess the full contractual cost and the implications of mileage changes or an early end.

The i4 comparison is worth doing separately when electric motoring is realistic. Include charging access, the type of journeys you repeat and the company-car position if applicable. Its Gran Coupe format may answer a different practical brief from the Convertible that first attracted you. Being clear about that change produces a better decision than assuming every 4 Series-shaped BMW is an equivalent substitute.

BMW 4 Series company-car tax across the lease

The petrol 4 Series requires a body-specific emissions calculation. A Convertible reference should not set the BiK for a Coupe, Gran Coupe or electric i4.

BMW’s current 420i Convertible technical reference gives 156-158 g/km, within the present maximum band, but other body and engine configurations require their own documents. The rows below show a lower-band example and the maximum path without assigning either to the complete catalogue.

When the car is privately available to a director or employee, P11D times the relevant percentage normally establishes the taxable benefit before income tax and adjustments. Options and engine-version changes matter. Compare this personal liability with the company’s commitments, then repeat the calculation for every tax year in the intended term.

These are conditional tax bands, not assigned rates for every BMW 4 Series. Confirm the supplied car’s P11D, certified CO2, fuel type and registration date. Diesel supplements can apply where the required emissions certification is absent, subject to the annual maximum.

Use our company-car BiK guide alongside HMRC’s 2026/27 and 2027/28 tables and the published 2028/29 and 2029/30 changes. Tax information checked 24 September 2026 against the C1 ledger and its primary sources. Tax treatment depends on individual circumstances and may change; consult your accountant.

Road tax and costs across the term

Vehicle Excise Duty (VED). For 4 Series, first-year VED depends on the supplied car’s CO2 and registration rules. The 2026/27 standard annual payment from the second licence is £200 before any supplement. Ask whether registration has already occurred and how road-tax changes are handled by the funder. Current annual figures should not be read as fixed for the whole agreement.

Expensive Car Supplement. A petrol or mild-hybrid car uses the Expensive Car Supplement threshold above £40,000 list price, including relevant options before discounts. The 2026/27 supplement is £440 a year for five years from the second licence. Compare the actual 4 Series specification with the official rules; an i4 has a different zero-emission threshold.

Planned eVED. The petrol bodies covered here sit outside the electric/PHEV categories of planned eVED. The government proposes April 2028 introduction at 3p per mile for electric cars and 1.5p for plug-in hybrids, subject to legislation and implementation, with CPI uprating from 2029/30. Include that separate exposure if the enquiry moves to i4. Later VED cash amounts remain unconfirmed here.

VAT and the business accounts

VAT-registered businesses can normally reclaim 50% of the VAT on qualifying car rentals where private use is available, depending on circumstances and the normal VAT rules. Full rental-VAT recovery requires exclusive business use with no private availability. Maintenance can fall outside the rental block when it is genuinely optional, separately described in the contract and separately quantified on the invoice; recovery remains subject to normal VAT rules. Read HMRC’s motoring VAT guidance.

The hire-cost rules normally disallow 15% of otherwise deductible rentals for cars above 50 g/km, subject to their scope and exceptions. A company-car BiK easement does not establish relief from this restriction. Check HMRC’s car-hire deduction rules.

For accounting periods beginning on or after 1 January 2026, revised FRS 102 generally requires a right-of-use asset and lease liability for lessees, including small companies using Section 1A. FRS 105 lease accounting for eligible micro-entities was not changed in the same way. Contract hire therefore does not universally keep a car off the balance sheet. Ask your accountant to apply the right framework; HMRC summarises the accounting standards.

Build the quotation around the way you will use it

Tell IVF your annual mileage, regular passengers, essential equipment, charging access where relevant and preferred timing. Ask for the precise model year, derivative, options and registration status to be written into the quotation. The catalogue is a starting point; the offered vehicle and funder terms need confirmation.

Business Contract Hire is taken by the business; Personal Contract Hire is taken by the private individual. Both are subject to status and individual funder criteria. Compare the initial rental, term, mileage, maintenance and applicable fees on the same basis. An initial rental is part of the hire cost, not refundable security or ownership equity.

A manufacturer warranty starts under the supplied car’s warranty terms, normally from first registration. Its time and mileage limits may finish before your lease does. It is separate from optional servicing and tyre cover. Confirm maintenance inclusions, insurance responsibilities, tax provisions and early-termination terms before signing.

At the end of contract hire, return the vehicle; there is no contractual purchase option. Excess mileage, damage beyond the funder’s fair wear and tear standard, missing equipment or other contractual charges may still be payable. Check the return process before choosing your agreement.
