The partnership will be solidified here.
When BMW and Jaguar Land Rover (JLR) first announced the companies would be working together on powertrain development, only electric power was talked about initially. The agreement between the two automakers later evolved to a "more far-reaching deal involving petrol (gasoline) diesel, and hybridized drivelines."
Now, according to Auto Express, we have the first news of a BMW engine going into a JLR vehicle. BMW's 4.4-litre twin-turbo V8 will apparently be used to replace JLR's ancient Ford-produced V8. On top of that, it will go into a hot version of the Defender expected to be called the Defender SVR.
According to the report, the high-performance Land Rover Defender is set to take on high powered SUVs like the Mercedes-AMG G63, and a running prototype is already in existence at Land Rover's engineering base in the UK. The V8 is reportedly hooked up to the standard eight-speed automatic gearbox and four-wheel-drive system but likely to gain a track mode option in the Terrain Response 2 system.
It's also mentioned that the Defender's all-new chassis is incredibly stiff and is making the job of tuning the chassis for a performance version easier than expected. That makes sense as Land Rover hasn't been using the traditionally stiffer body-on-frame engineered chassis type for some time for the Range Rover, but is still building an incredibly competent and robust off-roader.
BMW's twin-turbo V8 engine produces 567 horsepower and 553 lb-ft of torque in the X5 M SUV, and the standard M8 model has 600 hp. The Defender SVR is expected to keep its power close to the Mercedes-AMG G63's 577 hp.
The same engine is also expected to power several new JLR vehicles, so we can probably expect it to find its way into the next-generation Jaguar F-Type, the Range Rover SVR, and another top-spec Range Rover. If the insiders are correct, then we should see the Defender SVR in the metal towards the end of 2021.
