The wind has shifted for Britain's luxury carmakers a looming downturn in the convertible market threatens to dent revenues. Once a symbol of prestige and open-road freedom, convertibles are falling out of favour. Sales data from the Society of Motor Manufacturers and Traders reveals a 12 per cent year-on-year drop in convertible registrations for the first half of 2025. This is not a flash in the pan but a structural shift.
Consider the headwinds. Rising inflation and higher interest rates have squeezed discretionary spending. A convertible is a luxury asset, not a necessity. When the economy tightens, it is the first to be cut from the portfolio. The Bank of England's recent rate hikes have increased the cost of finance. For a vehicle that commands a premium of £15,000 over its hardtop equivalent, that premium becomes harder to justify.
Then there is the shift in consumer preference. The electric vehicle revolution has reshaped priorities. Range anxiety and charging infrastructure dominate the conversation. Convertibles, with their complex folding roofs and heavier frames, are less aerodynamically efficient. They sacrifice battery range for aesthetic appeal. Buyers are voting with their wallets, favouring SUVs and saloons that offer better utility and longer range.
British manufacturers are particularly exposed. Aston Martin, Bentley, and McLaren derive a significant portion of their sales from convertibles. Aston Martin's DB12 Volante, launched with much fanfare, now faces a lukewarm reception. The company's share price has fallen 15 per cent in the past quarter as investors discount future earnings. Bentley's Bentayga convertible, a niche product, has seen orders slow. McLaren's Artura Spider, its hybrid convertible, was supposed to be a game-changer. Instead, it has become a drag on the brand's transition to electric.
The secondary market confirms the trend. Prices for used convertibles have dropped sharply. A three-year-old Porsche 911 Cabriolet now fetches 8 per cent less than its coupe counterpart, a reversal of historical norms. This depreciation ripple feeds back into new car sales as buyers anticipate lower residual values.
What is the path forward? Some manufacturers are pivoting. Porsche has announced that the next generation of the 718 Boxster will be an electric model, hoping to reinvigorate the segment. But others are cutting their losses. Jaguar has shelved plans for a convertible version of its upcoming electric GT. The calculus is simple: allocate capital to higher margin segments.
The government's net-zero policies add another layer of uncertainty. Stricter emissions targets and the looming 2030 ban on new petrol and diesel cars create a regulatory fog. Convertibles, with their higher weight and drag, face higher penalties under these rules. The cost of compliance is passed to the consumer, further dampening demand.
Labour's proposed windfall tax on luxury goods, if enacted, would be another burden. The Treasury sees the luxury car sector as a cash cow. But tax a premium product and you risk killing the golden goose. Capital flight is a real concern. High net worth individuals, the core customers for these vehicles, are already looking to Switzerland and Singapore for more favourable tax regimes. If they go, the market goes with them.
The bottom line: the convertible is becoming a casualty of multiple forces. Economic headwinds, technological shifts, and regulatory burdens are converging. British luxury manufacturers must adapt or face a protracted downturn. The top is down, and the storm clouds are gathering.
