Automotive News has reported that the 2016 Cadillac CT6 will be equipped with a twin turbo V-6 (below). We wonder if this device will also power Opel’s possible future range topper, the revived Senator.
This is what Automotive News said: “[a] spirit of innovation will extend to the sedan’s powertrain, with General Motors announcing that an all-new 3.0-liter twin-turbo V-6 will be available under the CT6’s hood. The direct-injected V-6 is estimated to generate 400 hp and 400 pounds-feet of torque. At 133 hp per liter, Cadillac claims, the new engine is one of the most power-dense engines of its type. By comparison, the same-displacement inline six-cylinder found in the BMW 7 series, which is expected to be one of the CT6’s key rivals, generates 315 hp and 330 pounds-feet of torque.”
Thanks for those details. But you could have read that at AN yourselves (and if you haven’t, do). What is interesting for me is that this engine could very well also be used to propel a possible Opel Senator to be based on the Buick Avenir, should that make production. This will give a putative Senator a real USP in the market and allow it a fighting chance to compete with BMW, Audi and Mercedes.
I was wondering what other engines from the Opel range might be available to power a large car such as this hypothetical Senator. Looking at the on-line spec sheets I find a 1.4 Ecotec and and 1.6 Ecotec are doing service in the Insignia as base model engines, so it won’t be those. The 2.0 petrol and diesels are still there too but I can’t easily find the V6 that was there as recently as the autumn. With or without the Opel V6, the rest of their range of engines seems not to be up to the job so I expect that GM USA would be the source of the Senator’s power plants. For guidance, look to Cadillac’s range of units rather than to Russelsheim.
