The short answer
Based on available data, the Audi R8 comes out ahead of the McLaren 620R on fuel economy. 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
Extremely positive sentiment regarding the driving experience, emotional appeal, and V10 engine character, with the vehicle widely described as a childhood dream car. The R8 is praised for its engaging, analog feel, particularly in earlier generations, and its relatively accessible supercar ownership experience. However, owner discussions reveal significant and recurrent concerns regarding specific reliability issues, most notably with the magnetic ride suspension and the air conditioning compressor.
Best version to buy
For the first generation (2008-2015), a later model year (2014-2015) V10 with a manual transmission is frequently cited as the most desirable and reliable combination. The manual is strongly preferred over the earlier R-tronic and S-tronic automated manuals for longevity and driving engagement.
Known issues
Overall
