2008–2015
2015–2024
Two generations of Jaguar's executive saloon. The X250 brought V6 drama and classic styling; the X260 introduced aluminium construction and modern Ingenium engines. Here's which generation makes sense for your budget and driving style.
The X260 is the smarter buy for most buyers - it's lighter, more efficient, and its Ingenium engines (post-2019) are more reliable than the X250's ageing AJ126 V6 and Ford-sourced diesels. The X250 offers a more traditional Jaguar experience with its V6 soundtrack and hydraulic steering, but it's older, thirstier, and its cooling system failures are well-documented. For everyday driving, the X260 wins.

The X260 is the better choice for most buyers. Its aluminium construction makes it lighter, more agile, and more fuel‑efficient than the X250, and its Ingenium engines - especially the post‑2019 diesels - are more reliable and cheaper to replace than the X250's ageing AJ126 V6. The X260 also offers more modern technology and better refinement. However, the X250 has its own charm: a more traditional Jaguar feel, a wonderful V6 soundtrack, and a simpler, more analogue driving experience. If you value character over efficiency, the X250 is still a great car; for everyone else, the X260 is the smarter buy.
The X250 (2008–2015) was Jaguar's first‑generation XF, a car that reinvented the brand's saloon image. Its engine line‑up included the charismatic AJ126 3.0‑litre supercharged V6 (340–380 PS), a 2.2‑litre diesel from Ford, and a 3.0‑litre V6 diesel. The AJ126 is the star - it delivers a glorious supercharger whine and effortless performance - but it's known for cooling system failures, including water pump and crossover pipe leaks, which can be expensive to fix [PATTERN DATA]. The 2.2 diesel is robust but ageing, and the 3.0 diesel shares the 306DT's crankshaft bearing risk, though it's less common in the XF than in Land Rover applications. The X250's steel body means it's heavier than the X260, and its interior tech feels dated. Still, it offers a more traditional, engaging driving experience than its successor. Full specs and reliability ratings are on the AJ126 Knowledge Centre and 306DT Knowledge Centre.
The X260 (2015–2024) moved to an aluminium‑intensive architecture, shedding 190kg over the X250. Its engine range includes the 204DTD 2.0‑litre diesel (150–240 PS), the 204PT 2.0‑litre petrol (200–300 PS), a 2.0‑litre diesel from the Ingenium family, and a 3.0‑litre V6 diesel. The 204DTD is the volume engine; its pre‑2019 timing chain tensioner risk is well‑documented but substantially revised after the 2019 model year [EM‑INTERVIEW]. Replacement costs are moderate at £3,500–£5,800, significantly cheaper than the X250's AJ126 at £4,500–£7,500. The X260 also benefits from better fuel economy, sharper handling, and a more modern interior. It's the more sensible, refined, and cost‑effective choice for most buyers. Full details on the 204DTD Knowledge Centre and 204PT Knowledge Centre.
The X250's strengths are character and emotional appeal. The AJ126 supercharged V6 delivers a soundtrack and throttle response that the turbocharged Ingenium four‑cylinders simply can't match. The X250's hydraulic steering offers more feedback than the X260's electric system, making it feel more connected to the road. And the interior, while dated, has a classic, cosseting quality that some owners prefer. For those who buy a Jaguar for the driving experience rather than outright efficiency, the X250 is still a compelling choice. It's also cheaper to buy - a good X250 can be had for £4,000–£8,000, while an X260 starts at £8,000–£12,000. If you're on a tighter budget and don't mind the higher running costs, the X250 offers a lot of car for the money.
Over a typical 5‑year ownership window, the X260 is £1,500–£2,500 cheaper to run than the X250. This gap is driven by better fuel economy (the X260's lighter body and four‑cylinder engines save 10–15% on fuel), lower servicing costs (Ingenium engines are cheaper to maintain than the AJ126), and cheaper replacement parts when things go wrong. The X260 also has better residual values, meaning you'll lose less money when you sell. The X250's lower purchase price initially offsets some of these costs, but over five years the X260's running cost advantage is clear. Our engine replacement cost guide provides a full breakdown of costs for both generations.
Choose the X260. It's lighter, more efficient, and more reliable. The 204DTD diesel offers great fuel economy and a refined ride, making it perfect for daily driving.
If you value character and driving enjoyment, the X250 with the AJ126 V6 is the one to get. The supercharger whine and hydraulic steering make every journey feel special.
The X250 is cheaper to buy, but the X260 is cheaper to own. If you have a strict purchase budget, the X250 offers great value, but factor in higher running costs.
Whichever you choose, the same repair vs replace framework applies when the engine needs attention. Always factor in the vehicle's current value and the cost of a replacement engine.
Generally, yes - especially post‑2019 X260 models with the revised Ingenium diesel engines. The X250's AJ126 V6 is known for cooling system leaks, and its diesel engines have their own documented issues. The X260's aluminium construction also reduces wear on suspension components.
The X260's 204DTD is cheaper to replace (£3,500–£5,800) than the X250's AJ126 (£4,500–£7,500). Labour hours are also lower on the X260 due to better engine bay access.
Yes - if you're looking for a classic Jaguar experience on a budget. A good X250 can be found for £4,000–£8,000, and it offers a level of character and driving engagement that the X260 can't match. Just budget for higher running costs.
Jaguar uses a 60% scrap threshold: if the cost of a replacement engine exceeds 60% of the vehicle's market value, it's usually cheaper to scrap the car. We apply this rule in our repair‑or‑replace framework.
