The second generation Mercedes GLE is now a much stronger contender in the large luxury SUV segment thanks to smarter looks, more efficient engines and the option of seven seats for the first time. That's because it's significantly bigger inside than its predecessor, hence the bigger boot. The suspension's more sophisticated too and there are greater levels of safety and media connectivity. Rivals like BMW's X5 and Porsche's Cayenne must now take this car very seriously indeed.
