front and rear bumpers which became body-colored. New front and rear wings cover wider tracks and are re-profiled to a fuller shape compared to previous models, which feature a rolled lip. The 't' called attention to the car's new engine/transmission layout: the previously transverse engine mounted longitudinally while the gearbox remained transverse, thus forming a 't'. The 't' suffix was also homage to the first use of a transverse transmission by Ferrari in the highly successful Ferrari 312T, driven by F1 World Champion Niki Lauda. By adopting this layout, a longer engine could be mounted lower in the chassis, improving handling dramatically. The 't' configuration was used by Ferrari's Formula One cars of the 1980s, and would be the standard for the marque's future mid-engine V8 cars, beginning with the 348, introduced later in the year. The transverse manual gearbox fitted with a Limited Slip Differential with a twin-plate clutch design with bevel gears driving the wheels. Later in production, an electromechanical-actuated clutchless manual transmission, termed Valeo, was available as an option; where the driver would change gear using a traditional H-pattern gearshift, but the clutch was automatically actuated through electronic equipment, eliminating the need for a manually-operated clutch pedal. The new layout saw the engine and transmission mounted on a removable subframe; the assembly removed from the underside of the vehicle for maintenance. This process is necessary for timing belt replacement, making this a costly procedure for the owner who does not have a lift. On the other hand, the clutch was now located at the very rear of the drive train. This arrangement makes clutch replacement and service a simple, inexpensive, and readily owner-doable proposition. The engine was up to 3.4 L (3405 cc) and . The engine was controlled by Bosch Motronic DME 2.5 (later DME 2.7) electronic engine management that integrated EFI and ignition control into a single computer unit. Two of these were used in the car: one for each bank of the engine. Engine lubrication upgraded to a dry-sump system. The "t" was home to other Ferrari firsts: It used power-assisted steering for the first time and had a 3-position electronically controlled suspension for a variable tradeoff between ride quality and road holding. It also had a standard anti-lock braking system. The Mondial t represented the most substantial upgrade to the Mondial model line in performance and handling since its introduction in 1980. The
