Ford says that because the convertible was designed in tandem with the coupe, engineers were able to nearly double the torsional stiffness
of the underbody to make it the most solid and quiet Mustang convertible yet, while reducing added weight and cost.
Aerodynamic efficiency, courtesy of optimized trim and airflow - channeling elements which are fitted across the whole
of the underbody; provide a considerable degree of underbody sealing.
It does require the removable
of the underbody air valance.
Red tow hooks front and rear and a matte - black hood accent further differentiate the Trailhawk from the rest of the Compass line, while a hidden set
of underbody protection shields keep the engine, oil pan and gas tank from harm's way.
3rd Place: Lexus GX 460 What's Hot: Great daily driver, isolated cabin, enthusiastic drivetrain, efficient What's Not: Intrusive electronics, lack
of underbody protection, dull styling Our Take: A very good tool that has lost its edge From the Logbook:
Detailed management
of underbody and engine - room airflow, along with specific wheel designs, net further reductions in drag.
With standard front and rear locking differentials, the Ram Articulink suspension (with an electronically disconnecting front sway bar), Bilstein shock absorbers, an integrated 12,000 pound Warn winch and plenty
of underbody protection, the Power Wagon delivers the highest level of off - road capability in its class.
The sideskirts have also been further widened, a measure that has enlarged the overall surface area
of the underbody — for another increase in downforce.
The front of the car is dominated by a large grille opening and two support pylons for the aerodynamic double spoiler which channels air to the two radiators and generates suction that pulls air towards the central aero section
of the underbody.
The keys to successful rock crawling, rift straddling, and sand wrestling are steep approach and departure angles, a sturdy frame, and plenty
of underbody protection.
Despite its clean profile the Aston actually delivers genuine downforce, a feat that's been achieved courtesy of a front splitter, vents in the front wings, a number
of underbody channels and a huge rear diffuser.
A distinct lack
of underbody protection (illustrated most clearly by a low hanging exhaust box) and the fitment of road tyres confirm the really rough stuff is out of reach.
However, due to the design
of an underbody skid plate, debris could accumulate near the converter.
