A new teaser image of the MSB platform-underpinned Porsche Panamera has just been released, indicating the large four-door is edging closer to its launch. The short blurb accompanying the YouTube video talks about “more ideas per horsepower’, “engines that are more efficient, not bigger” and “the courage to change”.

It almost certainly points to engine downsizing, with the Cayenne and Cayenne GTS already sporting the marque’s new 3.6 litre twin-turbo V6. With the adoption of the new MSB platform also set to underpin the next Continental GT, it could also possibly use the 4.0 litre twin-turbo V8 currently seen in various Bentleys and high-performance Audis.

The 2017 Panamera appears to have received a more squared-off frontal treatment akin to the 718 range of Boxster and Cayman, while the rear light assembly in the teaser also shows sharper edges that bring the Panamera more in line with the current look of the 718 range and the updated, turbocharged Carreras.

The MSB platform, which will be applied to all high-end Volkswagen group models, is key to significant weight savings and therefore efficiency – the Panamera is said to benefit from it to the tune of 100kg. Autocar reports that the new Panamera’s template is based on advances made for the latest 911, which makes use of six different kinds of material, including magnesium, multi-phase steels and aluminium skin panels.

“Weight is our enemy and we are looking for the same percentage of aluminium as on the new 911,” said Wolfgang Hatz, Porsche technical head. “If you do nothing, the car becomes heavier and heavier. Comfort always equals weight, too.”

When applied to the Panamera, the weight-saving measures are said to ensure that kerb weight remains in the 1,800-1,900 kg range, to otherwise counter the weight gain from added luxury equipment and measures to comply with a new, non-regulatory US narrow-overlap crash test championed by consumer groups.
