Guide to long wheelbase cars

Holden makes long-wheelbase versions of its Commodore and calls them Statesman and Caprice

No, it doesn't mean a luxury version for the models they are based on are more than luxurious already. The L means long, or more correctly long-wheelbase.

Selected manufacturers take their luxury big sedans and stretch the wheelbase to create a long-wheelbase (LWB) model featuring enormous back-seat leg room. We're not talking about the almost-comical stretched limos here; they are custom modified. The cars we look at here are off the manufacturers' production line and can be ordered by any buyer at the dealer's local showroom. Any buyer with enough dollars, that is.


An LWB car can cost a round-figure half a million dollars the Mercedes-Benz S65 AMG in L trim is listed at $483,000 plus on-road costs (although it does come with a turbocharged V12, six-litre engine with Supercar-like 450kW power).

Rear legroom can come at a lower price, though. Holden makes long-wheelbase versions of its Commodore and calls them Statesman and Caprice, with a starting price of $63,990 which is a lot of car for the money, compared to the luxury brands.


The wheelbase is the distance between front and rear wheels. European car makers when stretching the wheelbase tend to give all the extra length created to the passenger cabin, particularly the rear seat area, leaving the boot unchanged at the tail of the car.  Jaguar XJ LWB has a 125mm longer wheelbase and the car grows by that amount too, while designers have created 134mm more rear legroom.

BMW 7 Series, Mercedes-Benz S-Class and Japan's Lexus LS600h have wheelbases of 140mm, 130mm and 120mm longer respectively, those measurements reflected exactly on the longer overall length of the car.

Holden is different in this regard. The wheelbase is lengthened only 94mm. Rear legroom is 97mm longer than the Commodore yet the car is a full 263mm longer, Holden being unusual in providing a larger boot in the extra length.

Indeed, if buyers want the most legroom in a Lexus, they will need to order an LS600h. The "h" indicates it is a hybrid which means electric motors and battery packs, which take up space in the boot. You get a 5.2m car with a 370-litre luggage space. Presumably, the wish to be more environmentally aware overcomes this. Also on Lexus LS600h, buyers can order a two-seat rear for an extra $5000. The rear three-seat bench is ditched an in go separate chairs with reclining ottoman and inbuilt massager.

It's usual for manufacturers to not only give more rearseat legroom on their LWB models but provide further luxuries, technology and convenience in the rear. After all, this is where royalty, rockstars, presidents and business tycoons will be sitting.

"The extended-wheelbase versions set new standards of rear-seat comfort," says BMW of its L versions of the 7 Series. "Both because of their enormously generous leg and headroom and because of the wide range of attractive communication, entertainment, climate control and seat comfort features.

"All extended wheelbase models come with a rear climate control package which allows each of two zones to be independently controlled in the rear.  The 750iL features rear Comfort seats with the option of massage and ventilation functions, headrest, backrest angle and seat cushion are all individually adjustable."

The priority of importance of the rear passenger in LWB cars is proven by some allowing the rear passenger to electronically adjust the position of the front passenger seat, for even more legroom.

Disadvantages of LWB cars? They are longer which makes them more difficult to kerb park and their longer wheelbase means they have the turning circle of the QE2. But at a stretch, they are kings of spacious luxury.
