The new RRS seems to be ok (except doors opening). However, it's using a similar motor and transmission to the the L320. OK the new ones got more power in the SDV6.
The Discovery Sport is having a few problems but fairly trouble free. LR used a similar motor, transmission, suspension & diff to the Evoque. The motor is moving to the new Ingenium motor.
The D4 didn't have any real dramas when released. However, again LR used a similar motor and transmission to the D3. OK the 3.0 sequential turbo was new. LR also used this strategy on the Evoque when they initially used a similar motor, transmission and diff to the Freelander 2.
I'm tipping the D5 will come out with a similar motor & transmission as the new RRS. The RRS will get the 6 cylinder Ingenium first. The D5 will probably have a cheaper high range version like the new RRS. IMO the D5 is likely to get the hybrid like the RRV & RRS. It's just good marketing.
