Destined to replace the existing TSX and TL models, the TLX debuts an even sharper evolution of the styling language introduced with the small ILX sedan in 2012.
Merging those model lines means that the TLX is shorter overall than the existing TL - the larger of the two current models - while riding on the same 2776mm wheelbase, ensuring comparable interior space.
This compromise also means that the TLX gets shorter - and sportier - overhangs at both ends, along with a lower and wider build than both of its predecessors.
As a 'prototype' concept, the TLX also gets 20-inch alloy wheels and a design-focused door mirror design. While these elements may be switched out in the lead-up to production, we expect the TLX to remain largely unchanged.
In production form, the TLX will get 2.4 and 3.5 litre petrol engines - likely Honda's new Earth Dreams range - along with an eight-speed dual-clutch auto for the smaller unit and the new ZF nine-speed auto for the larger.
Honda's Super-Handling All-Wheel-Drive system will also be offered, although exclusively with the 3.5 V6 models.
TLX... New Accord Euro?
The Acura brand remains off-limits to Australian buyers, but with the outgoing TSX doing duty here and in Europe as the Accord Euro, can we expect a similar arrangement with this new TLX?
That will depend partly on a right-hand-drive production plan for the TLX - an aspect that Honda and Acura have yet to comment on - but also on the already improved quality of Australia's new Accord sedan.
If a right-hand-drive version of the new TLX is confirmed, Honda's first focus will be on offering a new Accord Euro in the UK. In Australia, Honda will need to ensure that sales of the regular new Accord are not endangered.
Production capacity will also be a point of consideration for Honda: while the current TSX/Euro is built in Japan, the TLX will be built exclusively at Honda's Ohio plant in the US.
Expansion to overseas right-hand-drive markets could see Honda utilise its Japanese, European or Thai production plants, however.
