With the prototype of the car now revealed, here is a quick run down of the potential specifications:
- 2.4 liter "Earth Dreams" Direct Injection inline-4 cylinder mated to an 8-speed Dual Clutch transmission with torque converter
- 3.5 liter SOHC V6 mated to a 9-speed automatic transmission
- Both 2.4 liter and 3.5 liter engines will come standard as front wheel drive with Acura's Precision All-Wheel Steer (P-AWS)
- 3.5 liter engine will have the latest generation of Acura's Super Handling All-Wheel Drive (SH-AWD) as an option, and boasts a 25% weight reduction over previous generations of SH-AWD
- At 190.2 inches, the TLX is 3.8 inches shorter than the current TL, but will ride on a wheelbase that is the same 190.3 inch in length as the current TL
- Integrated Dynamics System (IDS) will be featured on the TLX, and will employee four driving modes: Comfort, Normal, Sport, and an all new Sport+ mode.
- A significant weight reduction over the last generation car is expected
- Improved aerodynamics for greater fuel economy and noise reduction
- The car will see some version of Acura's new electronic gear selector setup, which we saw on the RLX Hybrid
What follows are our impressions of the car, after stewing on it for the better part of today.

As promised, Acura said it would reveal two all new drivetrain options on the TLX prototype. Honda's "Earth Dreams" 2.4 liter inline-4 will be mated to an all new 8-speed DCT with torque converter and P-AWS, and the 3.5 liter V6 (most likely from the RLX) will be mated to an all new 9-speed automatic with your choice of P-AWS or SH-AWD. I was a bit disappointed in the engine choices, but not really surprised. As I had written in our Drawing Board of the TLX, I was hoping for the 2.0 liter turbocharged inline-4 currently being developed for the European and Japanese market Civic Type-R. It was obviously a long shot, but one can dream, right? The 3.5 liter V6 is definitely no surprise at all. Acura is basically stuffing this engine in to every car they have, and there is absolutely nothing wrong with doing so as it is a great engine. The question now is how much power each engine will be outputting.

Stuck in meetings all day, I also was not able to watch the reveal in real-time. However, Acura conveniently unveiled the photos and press release at the same time on the website and I was able to study those in detail on my phone. To me, the design is the best thing to come out of Acura's design studios since the last TL prototype was introduced over a decade ago. The front sports the now familiar Acura beak, but in its most refined version and carries the family resemblance to the ILX and RLX, flanked on both sides by the signature Jewel Eye LED headlamps. The compound curves in the hood add depth and meld smoothly into the tightly drawn shoulders of the front fenders.

In the rear, the taillights feel clean and derivative of the current TSX with just a touch of ILX and even a little Lexus IS. The short decklid is trimmed with a small lip spoiler, poised gently on the edge.

However, the sheet metal is pretty much done, as is typical of Acura's "concept" cars that they reveal at auto shows. What I see is a much more muscular version of the RLX's elegant, if bland, design treatment that has been adjusted slightly to offer a more athletic profile. Somehow, it just works and is the most cohesive design we have seen from Acura in a while. I am simply smitten with how clean, elegant, and athletic is feels and suspect that, like the design of the 3rd-generation TL, this car is going to age gracefully.
With limited information available about the interior (though all bets on it being very likely to look similar to the RLX's), the performance figures of the drivetrains, and how the car will actually drive, I reserve final judgment until I have a chance to get behind the wheel. However, what I see before me has a tremendous amount of potential and is genuinely a serious candidate for my next car, if the numbers are right. Fingers crossed that by the time production rolls around that a manual transmission will still make it into the mix, but if not, I just might be willing to accept the new 8-speed DCT.
