Almost certainly the longest car on display at the 2015 Geneva motor show will be this one - the 2016 Mercedes-Maybach Pullman. Its overall length of 6499mmm provides space behind an electrically-operated partition window for what Daimler AG justifiably calls a club lounge, with two extraordinarily luxurious 'executive seats' facing forward over enough legroom that there's room for two fold-down, rear-facing jump seats as well.
