Producing 342 hp (255 kW / 347 PS) and 516 lb-ft (700 Nm) of torque, the models have a 3.0-liter V6 TDI with 48-volt mild hybrid technology and an electronically powered compressor. This enables the cars to be approximately 19 percent more fuel-efficient than petrol-powered predecessors.
In terms of performance, the S5 TDI Coupe can accelerate from 0-62 mph (0-100 km/h) in 4.8 seconds. The S5 TDI can complete the same task in 4.9 seconds. Regardless of which model is selected, both have a limited top speed of 155 mph (250 km/h).
As with the S6 and S7, many non European markets will continue to receive the S5 with a 3.0-liter TFSI V6 engine. It produces 349 hp (260 kW / 354 PS) and 369 lb-ft (500 Nm) of torque. Despite having significantly less torque than the TDI variant, the petrol S5 Coupe can rocket from 0-60 mph (0-96 km/h) in 4.4 seconds and onto a limited top speed of 155 mph (250 km/h).
Regardless of where you buy your S5, all models will come equipped with an eight-speed tiptronic transmission and a quattro all-wheel drive system.
Getting back to the TDIs, they have a familiar exterior with a bright grille, faux aluminum accents and 18-inch alloy wheels. The models also come equipped with LED lighting units and a four-tailpipe exhaust system. Apparently, the facelifted model will be introduced sometime later.
The cabin comes nicely equipped with heated front sport seats, a leather-wrapped sport steering wheel and matte brushed aluminum trim. Customers can also order a 12.3-inch digital instrument cluster, a wireless smartphone charger and a Bang & Olufsen premium audio system.
Both models will arrive in Europe this May and German pricing starts at €65,300 for both the S5 Coupe and S5 Sportback.
