Default 2018 Buick Regal GS May Feature The Same Torque-Vectoring System As The Focus RS

Quote:
Holden’s next-generation replacement for the Commodore SS could come with the state-of-the-art all-wheel drive system that was developed for the Ford Focus RS, according to new reports.

Featuring full torque vectoring on the rear axle and a front electronic differential that helps manage torque across the axle to reduce understeer, according to Autocar GM European arm Opel will team up with engineering experts, GKN, to develop a rear-wheel drive biased all-wheel drive system.

That means the fastest Insignia VXR five-door liftback, that will be renamed the Commodore SS Down Under, should come close to matching the agility of the outgoing Aussie-made sedan with the security of all-wheel drive.

Despite no official confirmation from either GKN or Opel that the next Insignia VXR/Commodore SS will get the clever all-wheel drive system, branded Twinster, the engineering firm has already gone ahead and created prototypes, based on the current Holden Insignia VXR, to prove how effective the tech is.

Said to offer significant benefits over a normal all-wheel drive system the Twinster tech can apply torque to one or both wheels independently and can torque vector at any speed.

The system, originally developed for the Ford Focus RS, can also deliver far more torque to the rear wheels than its rivals. According to GKN the clever all-wheel drive has the ability to be able to drive the rear wheels faster than the front – hence allowing for oversteer or a controlled drift mode.

GKN says its system doesn’t rely on a vehicle’s braking system that can slow a vehicle down or cause significant brake wear.

Boosting agility further, is the next all-wheel drive Insignia VXR/Commodore SS will be up to 200kg lighter than the current model with the range-topping VXR or SS model weighing in at around 1600kg. Most of the weight-saving will come from using GM’s all-new E2XX platform that underpins Chevrolet’s new Malibu in the US.

2018 Buick Regal GS May Feature The Same Torque-Vectoring System As The Focus RS

If the 2018 Buick Regal GS ends up sharing similar hardware to its Vauxhall-Opel Insignia VXR/OPC cousins, enthusiasts could be in for a real treat.

AutoCar reports the next-generation Vauxhall Insignia VXR is set to use the same torque vectoring and all-wheel-drive system found in the Ford Focus RS. So, yes, the 2018 Regal GS could have a “drift mode”.

Supplier GKN has been working on adapting the system to the next Insignia VXR/OPC and currently has the system in place on a prototype 2016 Insignia VXR. The technology has been dubbed “Twinster”, and it allows for full torque vectoring at the rear. Drive to the front wheels utilizes a more commonplace electronic limited slip differential.

If we piece together rumors, intel, and connect a few dots, the 2018 Regal GS could be a twin-turbo V6, all-wheel-drive monster truly fit to wear the GS badge.

Vauxhall's next Insignia VXR will feature the same agility-improving torque vectoring technology as the Ford Focus RS when it arrives late next year.

The technical specifications of the 2017 sports saloon won’t be revealed for several more months, but GKN, the company that made the Focus RS’s all-wheel drive system, has been developing a current-generation VXR with its so-called Twinster module on the back axle. That suggests this drive technology is headed to Vauxhall’s upcoming all-wheel-drive car.

If rumours are right and GKN’s Twinster makes it onto the production VXR, it would enable full torque vectoring at the rear. Drive to the front wheels will be controlled using a more conventional electronic differential lock, which imitates a mechanical diff by braking wheels experiencing slip.



Autocar sampled GKN’s prototype at the Aldenhoven test centre in Germany. Initial impressions on the handling track confirmed the Twinster system improves throttle adjustability by increasing yaw angle under heavy mid-corner acceleration, but the car’s less active front drive system meant it still naturally pushed into slight understeer.

However, the next Insignia VXR will be much lighter than the 1825kg outgoing model — sources suggest a saving of 200kg — so there’s a strong chance this understeer can be dialled out.

No. Just because it may have GKN's Twinster RDU doesn't automatically make it torque vectoring.

Don't know about a GNX, but I've heard rumors of 5 doors.

A Buick would be the last nameplate I would expect this AWD system implemented seeing only 50+ year old people buy them.

I think people here are getting too exited over nothing.
This might be just a xdrive/quatro competitor, not a comeback of one of the greatest Buicks of all time.
Anyone here seen pictures of the GS? Definitely doesn't scream performance or excitement (unless you are a 60+ woman)

The new LaCrosse already gets GKN's Twinster. Why wouldn't the next Regal? It's also in the Envision, XT5, and Acadia.

But you have to be careful with the MKZ. I think both torque vectoring and base AWD are available with the 3.0L V6TT.

FOCUS RS: a hot hatch so revolutionary, so hardcore, its running the same awd system as your grandpa's, grandma's, great aunt's, and that crazy lady with 20 cats--Buick.

Sorry, couldn't resist--I am sure execution makes the difference... .

Something Ken Block will be hooning in a future installment of his videos, because that will be his market in just a little while.

these companies will sell you whatever hardware you want, but to get all the software and tuning done (to actually make it torque vectoring), you have to do it yourself or pay them $Texas

Default Buick Accidentally Reveals Regal GS With 3.6L V6 and AWD




Quote:
Buick Accidentally Reveals Regal GS With 3.6L V6 and AWD

by Steph Willems April 7, 2017

Can we call it a hot hatch? The next-generation 2018 Buick Regal bowed earlier this week in Sportback and TourX wagon form, but one variant was missing from the spotlight: the go-fast GS model.

While the existing Regal GS makes do with a high-output turbocharged four, a source told us last year the new Regal would offer six-cylinder motivation. So far, the launch date and the TourX wagon variant claims have come to pass, though there’s still no V6 Regal in sight.

Actually, there is. And it happens to be in plain sight.

Two days ago, the following paragraph appeared on the Regal landing page of Buick Canada’s website.

Buick Sportback GS mention on Buick Canada website

Engineered to make getting there all the fun, the all-new Regal’s excellent driving performance is something to be experienced with available new powertrain and AWD system (3.6L v6 on GS and Twin Clutch AWD).

Detailing the new model, the site touts the Regal Sportback’s GS variant, equipped with a 3.6-liter V6 and Buick’s twin-clutch all-wheel-drive system.

The mention then disappeared from the site.

Buick Regal GS screenshot

If you’re skeptical of the evidence so far, just search for the mention in Google. The GS mentions remains cached in the page description:

Buick Regal GS screenshot

A Buick spokesperson declined to confirm the authenticity of information on Buick’s website.



To date, the only engine announced for the Regal Sportback is a 250-horsepower turbocharged 2.0-liter inline-four. TourX models (which won’t be available in Canada) see torque boosted from 260 lb-ft to 295. Moving up to a V6 would give buyers at least 305 horsepower, going by the mill’s other applications. There’s also the possibility Buick could reach further into the parts bin and pull out the 335 hp variant found in the Chevrolet Camaro, giving the automaker added bragging rights.

With the 2018 Regal not expected on dealer lots until the fourth quarter of this year, Buick has plenty of time to schedule another product announcement.

TourX GS with the 3.6 and AWD? HHHnnnnggghhhhhh *splort*

I think the TourX is on my short list already, if it had the 3.6, it'd be top.

what difference does the powertrain make? judging by buick history, you already know the regal will weigh over 4K lbs. the best case scenario of a GM 3.6 that the article hopes for is only middle-of-the-pack competitive in an ats that weighs 3500 lbs

The new 2017 Opel Insignia which the new Regal is based off of, is ~300lbs lighter than the previous version.

So, around 3,175–3,635 lb between Opel versions.

Again, what GM is referring to as "torque vectoring" is not the same as the Focus RS. Yeah the torque is "vectored" between the rear wheels on demand. No it isn't an over-speed axle which increases wheel speed to induce yaw. It is a unique calibration to the AWD software to extract more performance.
