General Motors has announced today the Cadillac flagship model is programmed to enter production phase in the fourth quarter of 2015 at the Detroit-Hamtramck assembly plant.

GM is describing their new product as a "top-end, high-technology" Cadillac positioned above the CTS and XTS which will take the shape of a large sedan with a standard rear-wheel drive layout. The LTS is bound to ride "on a unique architecture" and will make use of "completely new, custom-designed materials" according to Cadillac President Johan de Nysschen.

The model will reportedly ride on GM's new Omega platform and will be offered with an optional all-wheel drive system. Power is expected to come from a V6 3.6-liter twin-turbo engine sourced from the CTS Vsport where it develops 420 bhp (313 kW) at 5,750 rpm and 430 lb-ft (582 Nm) of torque from 3,500 rpm.

To get ready for the model's arrival, General Motors will be making a $384 million investment and already they have installed new tools and equipment. The name of the car has not been revealed but according to some reports Cadillac will sell its range-topping model with the "LTS" moniker. We do know an announcement regarding the model's designation will be made soon and the vehicle will be revealed in full in the first half of 2015.
