Q Continuum: Infiniti Q50 to be unveiled at Detroit Auto Show

By Stephen Edelstein Published December 30, 2012

Infiniti has given the new luxury sedan it plans to unveil at the Detroit Auto Show a name. Called Q50, the new Infiniti will be the first car unveiled under the brand’s streamlined naming scheme. It will be revealed in the Motor City on January 14.

Beginning with the 2014 model year, all Infiniti models will be assigned an alphanumeric code beginning with “Q.” The Q50 will replace the current G sedan, with a Q60 replacing the G coupe and convertible down the line.

Often, the numbers in a luxury car’s “name” denote the displacement of the engine. In the current Infiniti lineup, a G37 is a G-series car with a 3.7-liter V6, and M56 is an M-series car with a 5.6-liter V8, etc.

That won’t be the case with the Q50; the current G is a relatively small car, so it wouldn’t make sense to equip it with a 5.0-liter engine, nor do any reports suggest that an engine the size of a Ford Mustang GT’s is in the works.

Instead, Infiniti is downsizing its engines. While explaining the name changes, Infiniti president Johan de Nysschen announced a new flagship sedan with a 550+ horsepower 3.0-liter V6. That’s a big step up in power, but also a big step down in displacement, from the aforementioned V8 in the M56. That engine produces 420 hp.

According to the Q-based naming scheme, the M56’s replacement will be called Q70. It seems likely that the Q70 will get the new 3.0-liter, or it may be reserved for an even larger range-topper. Either way, the Q50 could also lose some displacement compared to the current G37.

In addition to being the first new “Q” car, the Q50 is expected to be the first product of cross-pollination between Infiniti’s parent, Nissan, and Mercedes-Benz. Reports say Nissan’s venerable VQ V6 will be trashed for a Mercedes engine.

The Q50 could also be the first car to feature Infiniti’s “steer-by-wire” system, which uses a computer-controlled steering rack and sensors, eliminating the physical connection between the steering wheel and the road.

With so much newness crammed into one four-door chassis, the Q50 should be a very important car for Infiniti. We’ll see if the brand’s makeover was a success in the coming weeks.

EV sales surge could continue as Trump delays ending federal rebates, report says

A surge in sales of electric vehicles in the final months of last year could continue well into 2025, as consumers continue to take advantage of federal tax incentives while they last, according to a report by the Associated Press.
On the day of his inauguration, President Donald Trump signed an executive order titled “Unleashing American Energy”, which says the government is “considering the elimination of unfair subsidies and other ill-conceived government-imposed market distortions that favor EVs over other technologies.”
During his campaign, Trump’s team said it was planning to end the Biden administration’s $7,500 tax credit on the purchase or lease of an EV, although it did not provide a timeline for doing so.
Americans rushed to take advantage of the incentive, helping fuel a surge of more than 15% in EV sales in the fourth quarter, according to Cox Automotive.
Recent surveys show that incentives have played a major role in fueling EV sales over the past few years, and that a majority of Americans are in favor of government incentives to help with the purchase of an EV.
Meanwhile, the wording in Trump’s executive order, which says his administration is still 'considering' its options, leaves room for ambiguity about the timing of its application.
“Temporarily, sales of EVs could skyrocket as car-buyers rush to take advantage of existing tax credits,” the report by the Associated Press says.
In order to repeal the EV tax credit, the Trump administration will need to obtain the approval of congress. The process will likely take place as part of broader negotiations on extending Trump’s first-term tax cuts, which are due to expire near the end of 2025.
It’s also not entirely clear if the Trump administration will seek to end the whole of the $7,500 EV tax incentive. In order to obtain the incentive for the purchase of an EV, restrictions apply for high-income households and for EVs with non-U.S. made batteries. But those restrictions don’t apply to leasing an EV.
According to Cox Automotive, members of the Trump administration are particularly keen on ending “this leasing loophole, which was created partly to appease Korean and Japanese automakers, who have invested billions in U.S. EV manufacturing.”
Ending rebates and other subsidies for EVs is also likely to meet challenges, be they legal or political, from different actors.
The Zero Emission Transportation Association (ZETA), a trade group whose members include the likes of Tesla, Waymo, Rivian, and Uber, has come out in support of incentives for both the production and the sale of EVs.
ZETA says the incentives for both EV and battery-makers have led to enormous investments and job gains in Republican-dominated states like Ohio, Kentucky, Michigan, and Georgia.

Tesla Model Y Juniper vs Rivian R1S: Can Tesla’s newest take out a much more expensive vehicle?

Tesla Model Y 2025.

Tesla and Rivian actually have a lot in common. Both are relatively new companies in the grand scheme of things, at least compared to the legacy automakers that are now switching to EVs, but their actual vehicles are pretty different. The Tesla Model Y is the most popular electric vehicle in America, serving as a high-tech crossover for those interested in buying a Tesla. The Rivian R1S is Rivian's electric SUV, obviously boasting a larger body, but also putting tech first.

On top of the Tesla Model Y being the most popular EV right now, it's also in the midst of getting a major refresh in the form of the Model Y Juniper. We're still early on in the rollout of that refresh, though. While Tesla has released the Model Y Juniper in its base form in China, the version of the vehicle being sold in the US right now is the so-called Launch Edition New Model Y, which is a high-performance version of the Model Y Juniper that comes with a high price tag. For this comparison, we'll use the specs from the both the entry-level Model Y Juniper being sold in China, and the launch edition New Model Y being sold in the U.S. Keep in mind, however, that until the Model Y Juniper gets a wider U.S. release, only the previous-generation Model Y is being sold alongside the Launch Edition New Model Y

Tesla Model Y Juniper vs Kia EV9: Can the new Model Y beat a large SUV?

America's most popular electric vehicle, the Tesla Model Y, is getting a major refresh. Tesla already launched the Tesla Model Y Juniper in China, but now it's bringing the vehicle to the US.

Of course, the new Model Y has to go up against a host of competitive electric vehicles, some of which are larger, some faster, and some even cheaper. The Kia EV9 has been hailed for being one of the few full-size electric SUVs that offers a high-quality driving experience without completely breaking the bank.
