Why does this Cadillac fob seem to be for a mid-engine roadster?

Is GM bringing back its Caddied-up Corvette sibling, the Cadillac XLR — only this time based on the mid-engine Corvette? That's the question posed by photos of a wedge-shaped Cadillac key fob someone provided to The Drive. The buttons show a trunk — and also a frunk. So, mid-engine, unless the fob goes with an EV that has its motors and other electrical bits scattered to the wheels and elsewhere. Also, there's a button to operate a droptop. And the car profile on the fob is Corvette-like. All of which makes for some pretty great speculation. Except that Cadillac's way back from the failures of its sedan-centric lineup was thought to be through SUVs such as the new XT4 compact crossover, the XT5 and the somewhere-in-testing three-row XT6. Plus, the XLR, which was produced between 2003 and 2009, hit its sales peak in 2005 of just 3,730 cars, or about one-tenth the sales volume of the Corvette. So it's hard to imagine there's a vast untapped market out there for the luxury roadster — plus the XLR's demographic of well-to-do grandpas is dying off, or at least thinks it is. So a resurrected XLR would seem to be an unlikely savior. A lot's happening with GM's luxury brand — the debut of the XT4 at long last, a new boss, a thinning of the sedan herd but expansion of the V's, a backtrack to Detroit after its New York sojourn, the cash-cow Escalade under direct assault from the fine new Lincoln Navigator, and the impressive performance of its Super Cruise technology. But an XLR? So what is this fob's story? The Drive speculates it's a universal test fob and the buttons don't necessarily mean a thing, or that somebody stuck a Caddy emblem on it just to yank our chains. Who's to say. What would you like it to mean? Related Video:

Cadillac CT6 PHEV battery shape a big departure for GM's plug-in hybrid tech

Anyone with any familiarity with the electric powertrain details for the two General Motors plug-in hybrids will have noticed that the information we have about the newly announced Cadillac CT6 plug-in hybrid has a lot of numbers in common with the Chevy Volt and the Cadillac ELR, like the 18.4-kWh lithium-ion battery pack and an expected all-electric range of 37 miles. We also noticed that the announcement calls the plug-in CT6 hybrid an actual plug-in hybrid and not an "extended range electric vehicle (EREV)," which is what GM calls the Volt and the ELR. This, of course, means we needed to ask GM some questions. Donny Nordlicht from Cadillac communications told AutoblogGreen that while the Volt and CT6 batteries are both 18.4-kWh, the shape is completely different. In the Volt/ELR, the battery is T-shaped (see it here). The CT6 has four seats, with a tunnel running between the two in the rear, as you can see here, but the battery in the CT6 PHEV is "a cube-shaped pack, which is between rear seats and the trunk," Nordlicht said. "There is no pass through." GM has not yet released any technical schematics about this pack, but Nordlicht said that, "The CT6's advanced mixed-material platform was designed to accommodate the PHEV system by design so that it minimally intrudes on the cabin space." It also means that the CT6 can be ordered as an optional PHEV, while the Volt and ELR were purpose-built plug-ins. GM is also distinguishing between the EREV and PHEV powertrains in its vehicles from this point forward. "We are not discarding the EREV language," Nordlicht said. "The CT6 utilizes a two-motor system mated to a 2.0T 4-cylinder engine, which is an all-new system to Cadillac." We assume that the PHEV packs will use li-ion cells from LG Chem, just like the EREVs do, but Nordlicht did not answer our question on that point. As for other details about the CT6 PHEV – like production, full dimension, and pricing – we will just have to wait until closer to when the vehicle launches for those. Related Video:

Looking back on our favorite cars of Mad Men

The second half of the seventh and final season of Mad Men debuted this week, set to cap a run of public and critical acclaim. A decade's worth of interesting cars also made for good television, if you were paying attention. Vehicles didn't often steal the spotlight from Don, Betty, Roger, Joan and the gang, but they added meaningfully to the tone and beauty of the series. We sorted through the wheeled extras from Mad Men's archives, and choose some of our favorites to highlight. The list consists of cars that had at least a small impact on the plot of an episode, though certainly there are worthy gems hiding in just about every street and driving scene. Check out our subjective top five, and then let us know which of the Mad Men cars would be on your list. 1962 Cadillac Coupe DeVille – Season 2 Don Draper's Cadillac Coupe DeVille, all 500 feet of it, shows up in a few seasons of the show, but it's the first appearance that sets the tone. A Cadillac salesman, cut from the same cloth as Draper, asks what Don drives right now. "A Dodge," Don admits. "Those are wonderful if you want to get somewhere," allows the salesman, "this is for when you've already arrived." For a man on the move up corporate and social ladders that's a powerful message, and a pitch-perfect car. 1961 Lincoln Continental – Season 3 The most stylish Lincoln Continental ever is perfect set dressing for the mod show, of course. Though it's interesting that the car isn't cast as dapper Draper's ride, but rather his father-in-law's. Grandpa Gene does what all great grandfathers are bound to: lets his granddaughter Sally drive the big Lincoln while he works the pedals. Generational bond secured, in fine fashion. When you go back through the first three seasons of the show, you'll notice that Continentals show up more than once, too. There's nothing quite like them to evoke the best of the early '60s. 1963 John Deere 110 – Season 3 The only non-standard passenger vehicle on the list, no self-respecting gearhead/Mad Men fan should quibble with the inclusion of the John Deere 110 riding mower. For starters, the Deere is lovely to look at; a miniature version of the American Heartland icon in its green and yellow duds. The 110 appears as if milled from a solid block of steel, just the opposite of today's sleek, plasticky lawn minders (we're scouring Craigslist for one to bring home). The John Deere also has dear ramifications to the plot, too.
