Cadillac would still continue to produce coupes and wagons but they won’t anymore be both CTS models, according to Don Butler, vice-president of marketing for Cadillac. Although there is no confirmation that Cadillac would offer coupes and wagons under ATS, it seems that the alternative for either or both styles would be to be under the entry-level luxury model.
Should that happen, the number of body styles offered by Cadillac for the luxury segment would surely increase by two. Should Cadillac choose to offer ATS coupes and wagons, it could bring in more sales and at the same time send a signal that the brand and its product are strong. Cadillac currently offers the CTS in sedan, wagon, and coupe forms. The arrival of the entry-level ATS, the next-generation CTS will be more targeted to compete against the BMW 5-series and Mercedes-Benz E-class.
Cadillac, however, would not be enticed to build a large CTS coupe or any large variants, since they would surely be poor sellers. In fact, CTS’s rivals, the BMW’s 6-series and Benz’s E-class coupe, are abandoning larger variants and instead are being produced in smaller variants.
With this consideration, Cadillac might be forced to offer a two-door model to be offered between the ATS and CTS. In 2011, a source privy to the General Motors had revealed that the ATS will spin off a four-seat convertible positioned above the ATS but below the CTS.
The only possible way to do this is to build a hardtop coupe, which the company has confirmed. Hardtop coupes are becoming a thing for luxury carmakers: Audi has hardtop coupes for its A5 and S5, while BMW is rumored to offer a hardtop coupe in the persona of the 4-series.
The planned Cadillac coupe will likely don the same engines powering the ATS. Even when it may not be powered by naturally aspirated 2.5-liter four that runs the starting variant for the ATS, the new coupe may be fitted with the 270-hp turbo four and 318-hp V-6. The coupe and convertible may also don the same 400-hp engine that will power the planned ATS-V. [source: Caranddriver]
