In an automotive world buzzing with the hum of electric motors and the promise of a zero-emission future, the familiar grumble of the diesel engine seems like a sound from a bygone era. Yet, for a significant portion of drivers, diesel power remains the undisputed champion of torque, towing, and long-distance fuel economy.

While many manufacturers are winding down their diesel development, 2025 is shaping up to be a year of defiant launches. These aren't just old models lingering on; they are new-generation and significantly updated vehicles where the diesel engine has been refined, often with mild-hybrid technology, to be cleaner and more efficient than ever. Here are the top new diesel car launches to keep an eye on in 2025.

1. The All-New Skoda Kodiaq

The first-generation Kodiaq was a massive success for Skoda, offering incredible space, practicality, and value. The all-new second-generation model, set to hit full stride in 2025, continues this legacy and defiantly retains a diesel powertrain.

The star of the show will be the latest evolution of Volkswagen Group's 2.0-litre TDI engine. Available in various power outputs and with the option of 4x4, this engine is the perfect partner for a large, seven-seat SUV. It promises effortless cruising on the motorway and the stump-pulling torque needed for towing a caravan or boat. For families who undertake long holiday drives or live in rural areas, the new Kodiaq's diesel option makes it an almost unbeatable package.

2. The Next-Generation BMW X3

BMW has long been a master of the diesel engine, creating powerplants that are not only powerful and efficient but also surprisingly smooth and refined. The next-generation BMW X3, expected to be fully revealed for the 2025 model year, will continue this tradition.

While a fully electric iX3 will be a headline act, sources confirm that powerful and efficient diesel options will remain. Expect to see the return of the beloved xDrive20d and the formidable xDrive30d models. These engines will likely be paired with a 48V mild-hybrid system to improve fuel economy and reduce emissions, ensuring they meet modern standards while delivering the performance and 500+ mile range that X3 owners love. It’s the ultimate driving machine for those who need to cover serious distance.

3. The Updated Land Rover Defender

The Land Rover Defender is a modern icon, blending legendary off-road capability with on-road comfort. For many of its intended uses—overlanding, towing, and conquering the countryside—a diesel engine is simply the right tool for the job.

For 2025, the Defender is expected to receive a model year update, which will include tweaks to its interior tech and powertrain options. The excellent 3.0-litre six-cylinder Ingenium diesel (D250, D300) will continue to be a cornerstone of the range. This mild-hybrid engine is a masterpiece, providing a wave of smooth, accessible torque that makes off-roading feel effortless and towing heavy loads a breeze. It proves that for a vehicle built for adventure, diesel is far from dead.

4. The New-Generation Toyota Hilux

The Toyota Hilux is a byword for indestructibility. In markets across Europe, Australia, and Asia, its diesel engines are a key part of its legendary status. A new generation of the Hilux is on the horizon, and it's set to bring its diesel powertrain into the modern age.

The big news is the introduction of a 2.8-litre diesel engine with a 48V mild-hybrid system. This technology doesn't just aim to reduce emissions; it also promises to improve throttle response and provide smoother acceleration. For a workhorse vehicle relied upon by tradespeople and adventurers alike, this updated diesel engine will enhance its capability while improving running costs. It’s reliability, electrified.

Why Is Diesel Still Here?

In the age of electrification, the persistence of these diesel models comes down to three key factors:

1. Unmatched Torque: For towing heavy trailers, caravans, or horseboxes, the low-down pulling power of a diesel engine is still superior to most alternatives.
2. Long-Distance Efficiency: Diesel engines remain more fuel-efficient than their petrol counterparts on long, steady motorway journeys, offering extensive range between fill-ups.
3. Infrastructure and Use Case: For drivers in rural areas without easy access to EV charging or those who need a rugged, go-anywhere vehicle, diesel remains the most practical and reliable choice.

While 2025 may represent one of the last major waves of new diesel vehicle launches, it's clear that for the world's most demanding driving tasks, the diesel engine still has a vital role to play.
