The 2019 Nissan Maxima isn’t dramatically different from its last two predecessors with regards to performance or fuel efficiency. However, at 300 HP (and 261 lb-ft of torque) the base model’s naturally aspirated 3.5L V6 wasn’t exactly lacking power.
Changes to the 2019 Maxima are mostly on the exterior and include all-LED headlights and tail lights, four exhaust tips, Safety Shield 360 (as an option), a redesigned front grille and bumper.
With regards to the benefits offered by LEDs, one of the biggest is energy efficiency. Conventional incandescent bulbs provide 10-15 lumens of brightness for every Watt of power they draw, while LEDs usually provide 80-100 lumens per Watt. The impact on your fuel economy is a different matter.
This also means that brighter LEDs can be installed in the same headlight housing without exceeding the 55-Watt or 60-Watt limit (bear in mind that you first need to confirm that whichever brightness you desire is legal in your jurisdiction).
Safety features offered with the Safety Shield 360 option include automatic emergency braking, automatic high beam headlights, lane departure warning, blind spot monitoring, among others.
The car has 14.3 cu-ft of cargo room, a CVT transmission, it gets 20 MPG during city driving, and 30 MPG during highway driving. If driving in the city, this isn’t going to be economical, but luxury cars rarely are.
The reason that highway fuel economy is better is due to less braking and acceleration on highways, both of which waste fuel. City driving entails frequent braking and acceleration due to numerous stops and turns. The 2019 Nissan Maxima goes on sale in December 2018.
