First Cadillac ELR rolls off the line

Gearing up for the Belle Isle Grand Prix this weekend, General Motors invited some of the Chevrolet and Cadillac racecar drivers out to its Detroit-Hamtramck assembly plant. While there, the racers - including IndyCar Driver and Chevrolet Volt owner, Simona De Silvestro - witnessed the very first 2014 Cadillac ELR to roll off the assembly line.
These vehicles are not destined for customers, however, but instead pre-production units will be used by engineers for testing purposes. Actual production of ELR consumer models is expected to commence closer to the end of this year. As a refresher, this range-extended electric Cadillac shares much of its powertrain with the Volt but will have a sportier coupe design inspired by the Converj Concept. De Silvestro manged to snap a few images of here own, which you can see in the gallery below.

GM Design shows what could have been and what might be

We periodically like to check in with GM Design's Instagram account to see what they're cooking up. Even better is when we catch a glimpse of an alternate history of what legendary designers from The General's past were thinking, though those ideas may not have made it into production. This week, for example, the account posted some illustrations from George Camp, whose career at GM spanned nearly four decades, from 1963 to 2001. One of the renderings is of what appears to be a 1971-72 Pontiac GTO Judge, but with two headlights instead of the production unit's quad beams. The rear departs from the canonical version most dramatically, with a massive integrated wing. Other bits that didn't make the production cut include large side vents, a gill-like side marker and rectangular intakes below the headlights that wouldn't be out of place on a modern design today. Amazingly, from what we can make out of the date, it appears that the drawing was done sometime in 1965, which makes it quite prescient.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) There's also a very aerodynamic interpretation of a Corvette ZR-1. To our eyes it splits the difference between the 1986 Corvette Indy concept and a fourth-generation F-body Pontiac Firebird, so perhaps parts of Camp's work on this sketch did make it into physical form. There's also a radical sports car concept from May 1970 that resembles the Mazda RX-500 concept from the same year, a Syd Mead-looking Cadillac coupe, and an Oldsmobile with a cool take on the company's trademark waterfall grille and elements of the Colonnade Cutlass at the rear. Other recent posts include a FJ Cruiser-like off-road EV, a sleek coupe with the Chevy corporate grille, and a rendering of a Silverado-esque pickup that looks far better than the current production version.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) It's pretty easy to lose hours in the account, but it's always fascinating to see GM's visions of what could have been and what might be.

Cadillac previews CT6 interior and its 34 Bose speakers

We get an early monochrome look at the upcoming Cadillac CT6 interior thanks to its stereo system. Bose will debut its Panaray Sound System in the flagship sedan and have 34 speakers located throughout the cabin that will have the occupants bathing in sound. A close look at the interior mock-up shows little visible difference between the CT6 and the praised CTS; the only thing we could find was that the headrests are slightly different and the seat switches have been moved to the doors, a la Mercedes-Benz. As for that Panaray, Bose says it incorporates elements from the company's home and professional audio products, and was designed "exclusively" for this car. We don't know if that means it was tuned for the CT6 or that it will only ever be available on the CT6. Nor do we have any detailed specs on it at the moment, but there's a press release below with a few more tidbits and a high-res graphic above with details on each speaker. Bose Introduces First-of-its-Kind Panaray® Sound System for First-Ever Cadillac CT6 Advanced automotive sound system integrates elements from home products DETROIT, 2015-03-26 – Thirty-five years ago, Bose and Cadillac defined premium automotive audio, forever changing how people listen to music in a vehicle. Now Bose is introducing its most advanced and highest-performing automotive sound system – the Bose® Panaray® system, designed exclusively for the Cadillac CT6 sedan. The 2016 CT6 is a first in its segment, combining the prestige and technology of a range-topping vehicle with the dynamics and efficiency of a smaller one. The Panaray system marks the global debut of Bose Automotive's new line of "Advanced Technology Series" sound systems, integrating technologies and design elements from Bose home entertainment and professional audio products to deliver unprecedented performance in a car. "We asked Bose to create something truly special for this new vehicle: an unbounded sound system, providing an audio experience unmatched in any other luxury automobile," said Travis Hester, Cadillac CT6 executive chief engineer. "Cadillac CT6 customers will be elated by what they hear and feel when they switch on the Bose Panaray system." The Bose® Panaray® system reproduces music with more clarity, precision and deep bass than any system preceding it.
