The short answer
Based on available data, the Jaguar XE comes out ahead of the Lexus IS on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Mixed sentiment with a clear generational divide. The driving experience is consistently praised as a major strength, with owners highlighting nimble handling, balanced agility, responsive steering, and a truly dynamic feel in sport modes. The design and styling are also frequently cited as positives, offering a rarer, more distinctive alternative to mainstream German competitors.
Best version to buy
The post-2019 facelift model is strongly recommended over the first generation (2015-2018) due to corrected flaws and improved reliability, particularly regarding the timing chain issue on diesel engines. For engines, the 3.0-liter supercharged V6 petrol (XE S) and the 2.0-liter petrol units are viewed as much safer and more reliable choices than the early 2.0-liter Ingenium diesels.
Known issues
Overall
Mixed sentiment heavily dependent on generation and powertrain. The IS is widely recognized for its strong long-term reliability, comfortable ride, and luxury feel, particularly when compared to German competitors. However, significant and recurring criticisms are directed at specific mechanical flaws, outdated powertrains, and poor fuel economy.
Best version to buy
IS 350 with the 2GR-FSE V6 engine is the most frequently recommended version for its superior power and reliability over the IS 250. For the third generation (3IS, 2014+), the 2015-2016 model years with the V6 and 6-speed automatic transmission are specifically highlighted to avoid the later UA80 transmission used in 2017+ models.
