Our spies have managed to catch the 2014 Cadillac CTS undergoing testing near the Nürburgring.

The 2014 Cadillac CTS has been spied near the Nürburgring.

While the prototypes are heavily disguised, we can see the model will have evolutionary styling that embraces the Art & Science design philosophy. Notable highlights include a prominent grille, a shark-fin antenna and trapezoidal exhaust tips.

Underneath the edgy bodywork, we can expect an extended version of the Alpha platform that currently underpins the ATS. This will result a roomier cabin which is more comparable to the Audi A6, BMW 5-Series and Mercedes E-Class.

Engine options remain unconfirmed, but speculation suggests there will be a 2.5-liter four-cylinder with 200 hp (149 kW / 203 PS), a turbocharged 2.0-liter four-cylinder with 270 hp (201 kW / 274 PS) and a 3.6-liter V6 with 320 hp (239 kW / 324 PS). A diesel engine will eventually be offered in Europe, but there's no word on specifications. We can also expect another CTS-V which could use a supercharged 6.2-liter V8 engine that produces more than 556 hp (415 kW / 564 PS).
