What are the differences between the 16 and 18 models of the Alpha?
3 Answers
Toyota does not have a model called Alpha, only the Alphard. There is no 16 model of the Alphard, only the 15 model. Here is a detailed comparison between the 15 model and the 18 model: Engine: The 18 model's engine code is 2GR-FKS, while the 15 model's engine code is 2GR-FE. The 18 model's engine features hybrid injection technology, whereas the 15 model's engine uses multi-point electronic fuel injection. The 18 model's engine has higher maximum horsepower and torque compared to the 15 model. Transmission: The facelifted 18 model is equipped with an 8-speed automatic transmission. The 15 model is equipped with a 6-speed automatic transmission. Seats: The second-row seats in the 18 model offer more adjustable functions, including forward/backward adjustment, backrest adjustment, height adjustment, and leg rest adjustment. The 15 model's seats have fewer adjustable functions. High beams: The 18 model's high beams are LED, and the car is equipped with ambient lighting. The rear seats have heating functions, and the multimedia entertainment system is more advanced. The 15 model's related configurations are inferior. Other: Compared to the 15 model, the 18 model features a 360-degree panoramic camera, a rear cross-traffic alert system, a panoramic sunroof, ventilated front seats, and other functions.
I've driven my friend's 2016 and 2018 Alphards, and the difference is quite noticeable. The 2018 model's most significant change is the front grille, which switched from horizontal bars to a honeycomb pattern, with sharper fog light housing designs that make it look much younger. For the interior, the base model upgraded the steering wheel material and optimized seat support, especially with thicker padding in the second-row airline-style seats. The hybrid version is the key difference—the 2016 model only had a 3.5L naturally aspirated engine, while the 2018 model introduced a 2.5L hybrid system for the first time, achieving fuel consumption as low as 6L, which is particularly economical for city driving. Safety upgrades are also worth mentioning: for example, the pre-collision system evolved from the 2016 model's single-lens camera to a dual-sensing setup with millimeter-wave radar and camera, improving pedestrian detection sensitivity. In terms of resale value, used 2018 hybrid models now command about 5% higher prices than their gasoline-only counterparts from the same year, so I'd recommend prioritizing hybrid models when buying used.
In terms of technical specifications, the 2018 model features minor chassis adjustments. The front suspension spring rate (K-value) has been increased by 10%, making it more responsive over speed bumps while maintaining refined vibration absorption on rough roads. Although both models use a 3.5L V6 engine, the 2018 version's optimized ECU programming delivers approximately 8% more torque below 2,000 rpm, improving urban driving agility. The transmission logic has also been enhanced – while the older model would hesitate for half a second when flooring the accelerator, the new version downshifts significantly faster. Lighting has been upgraded to full LED across the range (only the 2016 high-end trim had LED low beams). The infotainment system remains a weak point: the 2016 model only had a CD head unit, while the 2018 version finally got a 7-inch touchscreen but still lacks CarPlay support. For modifications, note that the 2018 model's grille and bumper mounting points have changed, making aftermarket parts from the older model incompatible.
