What's in a name?

3.5 liters. That's the most popular engine displacement out there. Every major automaker has at least one engine in this size category, virtually all of them 6-cylinder engines. Who has it? GM: 3.5 L "High Value" OHV V6 (Chevrolet Malibu, Pontiac G6) Toyota: 3.5L DOHC V6 (Toyota Avalon, Lexus RX350) Honda: 3.5L SOHC V6 (Honda Pilot, Acura RL) Nissan: 3.5L DOHC V6 (Infiniti G35, Nissan Altima) Hyundai 3.5L DOHC V6 (Hyundai Santa Fe-2006) Chrysler 3.5L SOHC V6 (Chrysler Pacifica, Dodge Magnum SXT) Mercedes 3.5L V6 SOHC (Mercedes E350, Mercedes ML350) This is soon to be joined by Ford's new (and long-overdue) 3.5 L V6, which will find its way into some of its new midsize sedans and even some Mazdas. This invariably leads to a bit of a squeeze when coming up for names of vehicles equipped with such engines, especially if it's a luxury vehicle. Ford instance, you have the Nissan 350Z and of course the Mercedes E350. Until last year, Hyundai's large sedan was known as the XG350. Now Lexus joins the fray with the ES350, RX350 and IS350. Huh?
