It represents a 3.5-liter engine equipped with twin turbochargers. The 3.5-liter engine has 6 cylinders and delivers robust power. Models using the 3.5tt engine include the Ford Raptor, Lincoln Navigator, and Ford Expedition, among others. Below is relevant information: Lincoln Navigator's body dimensions: The vehicle's length ranges from 5355 mm to 5657 mm, width is 2073 mm, height ranges from 1937 mm to 1934 mm, wheelbase ranges from 3112 mm to 3342 mm, minimum ground clearance ranges from 200 mm to 204 mm. The vehicle is a five-door, seven-seat SUV with a fuel tank capacity of 89.3 liters to 105.2 liters and a cargo volume ranging from 343 liters to 2947 liters. Raptor's chassis and steering system: The model features a front-engine, four-wheel-drive layout with part-time four-wheel drive and an optional on-demand four-wheel-drive system. It uses a multi-plate clutch central differential, with an independent double-wishbone front suspension and a leaf-spring non-independent rear suspension. It employs electric power steering and has a unibody construction.
In my experience, 3.5tt typically refers to a 3.5-liter twin-turbocharged engine, a configuration commonly found in many performance cars or luxury SUVs. 'tt' stands for twin turbo, meaning two turbochargers are used to handle different RPM ranges—one activates at low RPMs while the other kicks in at higher RPMs. This setup reduces turbo lag and enhances overall power output. For example, models like the Infiniti QX60 or some high-performance Nissan vehicles have used such engines, delivering an exhilarating driving experience with strong acceleration and noticeable g-force. However, the twin-turbo design also means higher maintenance costs, as turbo components are prone to carbon buildup and require regular servicing, avoiding prolonged idling. From a market perspective, while many automakers are shifting toward hybrid or electrification, the 3.5tt remains highly popular among drivers who pursue pure driving pleasure.
I often see people asking about 3.5tt on forums. Simply put, it refers to a 3.5-liter displacement engine with a twin-turbocharging system. The 'tt' stands for twin turbo, and this dual-turbo layout effectively reduces the hesitation during startup, making acceleration smoother. In actual driving, some high-end models like Lexus use this type of engine, which provides ample power while maintaining good fuel efficiency, making it particularly suitable for long-distance travel or highway cruising. Compared to single-turbo or naturally aspirated engines, it offers more immediate response, but the downside is slightly higher maintenance requirements, such as paying attention to turbo cooling issues. Overall, if you prioritize daily practicality and reliability, the 3.5tt is a solid choice in the family car segment.
