Tata Motors (part of the massive Tata Group conglomerate) purchased both Jaguar and Land Rover from the Ford Motor Company in 2008 for roughly $2.3 billion. In 2013, Tata officially merged the two storied British icons into a single composite company called Jaguar Land Rover Automotive PLC.

While ownership is based in India, the vehicles are still primarily designed, engineered, and headquartered in the United Kingdom.

The “House of Brands” Structure

If you are looking at live data for oil dilution, you are likely dealing with one of their modern models. JLR operates under a “House of Brands” design approach, separating their lineup into four distinct vehicle pillars:

• Range Rover (e.g., Evoque, Velar, Sport, Vogue)
• Defender
• Discovery (and Discovery Sport)
• Jaguar (e.g., F-Pace, E-Pace, I-Pace, and their sedan legacy)

1. The Range Rover Family

• Range Rover (Flagship / Vogue): The full-size ultra-luxury model.
• Range Rover Sport: The mid-size, performance-oriented version.
• Range Rover Velar: The sleek, style-focused crossover.
• Range Rover Evoque: The compact, urban luxury SUV.

2. The Defender Family

• Defender 90, 110, & 130: The rugged, boxy off-road icons. Heavy use of the post-2020 hybrid systems.

3. The Discovery Family

• Discovery: The full-size, family 7-seater.
• Discovery Sport: The smaller, more affordable compact version.

4. The Jaguar Family

• F-Pace & E-Pace: The mainstream luxury SUVs (the mechanical twins to the Velar and Evoque).
• I-Pace: The bespoke all-electric SUV.
• XE & XF: The brand’s traditional luxury sedans.
