There a many cars that get great gas mileage. Many are even affordable, fun to drive, and reliable too. The problem is that if you need transportation for a family of 6 or more, many of these vehicles just don’t cut it. A Mini Cooper S may be a great car for the daily commute or running a canyon road, but trying to fit a family of seven in one is akin to practicing for a circus act.

What do you do if gas bills are killing you, but you really can’t drive a Honda Fit, Mini Cooper, or Prius Hybrid? What if your transportation duties run the gamut, from running 3 or 4 kids to school, soccer or swimming, picking up 10 bags of groceries, and running the whole family for weekend trips to Grandma’s? Even a normal sedan, such as an Accord or Taurus just isn’t big enough.

Here are the top vehicles to drive if you have to move more than the average number of people and their gear.

Best Gas Mileage Vehicles to Buy if You Have a Large Family #6

2009 Chrysler Town and Country Minivan – 4.0L V6, 6-sp auto, 17city / 25highway / 20 combined MPG, Base MSRP: $24,195.

The latest from the ones who started the minivan revolution (but didn’t actually invent it, that goes to VW), the latest Town and Country comes in at number 7 on the list. It also demonstrates the importance of an advanced transmission (see my post on technology to increase fuel economy) in the quest for better gas mileage. The 4 liter engine with the 6-speed actually gets better EPA fuel economy ratings than it’s smaller engined counterpart, which is mated to only a 4-speed auto.

The relatively good mileage, coupled with the utility of such innovations as Chrysler’s “Stow-n-Go” seating make this one a winner if you have a large family and need to get them around town.

2009 Ford Flex Crossover SUV, FWD – 3.5L V6, 6-sp auto, 17 city / 25 highway / 19 combined MPG, Base MSRP: $28,295.

One of the main reasons so many drivers eschewed minivans in favor or SUVs in the last decade and a half is that they don’t want to be perceived as dowdy, un-cool, or devoid of style. Well driving the new Ford Flex definitely won’t get them pigeonholed into any of those categories. It drips of style, but still delivers enough room inside to get the whole brood to their little league practice and the swim meet without having to sit atop one another.

The Flex is a (very) modern interpretation of something right out of So Cal in the ‘50s. It’s not a minivan, but replaced on in Ford’s lineup, the never really popular Freestar. In a land of all the same, derivative products, Ford looks to have broken the mold for large family transportation. All that and it has suicide doors and returns very respectable gas mileage for a quasi-large people mover.

Best Gas Mileage Vehicles to Buy if You Have a Large Family #4

2009 Mazda 5 Minivan FWD – 2.3L I4, 5-sp auto, 21city / 27 highway / 23 combined MPG, Base MSRP: $18,665.

The 2009 Mazda 5 has one real ace in the hole; great fuel economy for a vehicle that can hold your entire family. It also looks pretty cool, with little of the boring, me-too styling that so many others in the genre find themselves draped in, and you can get one at a bargain price compared to other vehicles that can hold 6 people. It has two things going against it that kept it from finishing higher in this list of great vehicles for transporting a large family while getting excellent MPG; it really isn’t that large, and it really isn’t that quick. In fact part of the reason it gets such great fuel economy is a result of precisely those two traits.

If you have a family of 6, and 2 of the family members are small kids, this will definitely do the trick. It handles well, a hallmark of most Mazda products, and should be very reliable, if past reliability stats are any indication. If your group includes teenaged twins that happen to play tight end on the high school football team and a few more kids over about 10 years old, you should probably find another mode of transportation however. The Mazda will simply be too tight of a squeeze.

Best Gas Mileage Vehicles to Buy if You Have a Large Family #3

2009 Chevrolet Traverse FWD – 3.6L V6 direct injection, 6-sp auto, 17city / 24 highway / 19 combined MPG, Base Price MSRP: $30,810.

The Chevrolet Traverse is the latest iteration of the GM large SUV platform that’s also spawned the GMC Acadia and the Saturn Outlook. It’s modern, with a 3.6 liter V6 that includes direct injection fuel delivery, one of the reasons a 288hp vehicle that transports 8 full sized people can get such good gas mileage (for this sized vehicle). The interior is modern as well, proving again that American vehicles can deliver in this department, even if it took 30 years for U.S. automakers to figure it out.

The 2009 Traverse has a great combination of ride and handling for such a large vehicle, and is by most reports, relatively quiet too. All in all it’s a great place to spend time on a long road trip with the entire family, providing you can still afford to take one, with the high price of fuel these days. At least the Traverse burns regular gas, currently the least expensive liquid motivator you can get at the local filling station.

Best Gas Mileage Vehicles to Buy if You Have a Large Family #2

2009 Honda Odessey LX Minivan FWD – 3.5L V6, 5-sp auto, 17 city / 25 highway / 20 combined MPG, Base MSRP (LX version): $26,255.

Honda has wrought a vehicle that consistently finishes at the top of its class with the Odyssey minivan. Honda has always created spectacular power plants, and the 3.5 liter in the Odyssey is another example of one of their sewing machine smooth, internal combustion, creations. The only nits that kept this one from finishing even higher on the list is that it’s a mite noisy on the freeway and could be a bit larger if you’d like to transport 7+ people. It has a cockpit that is a fantastic place to spend time, with everything falling readily to hand, and large, easy-to-read instrumentation that’s been a hallmark of Honda binnacles since the early ‘80s. The Odyssey even handles fairly well for vehicles in the minivan category.

Best Gas Mileage Vehicles to Buy if You Have a Large Family #1

2009 Chevy Tahoe SUV Hybrid 4×2 – 6L V8, CVT, 21 city / 22 highway / 21 combined, Base MSRP: $50,490.

The new hybrid Tahoe is a technological tour de force, enabling a huge, vehicle with a 6 liter V8 engine to return 20mpg. If you have to have a large vehicle to transport 8 people, and all their stuff, on a long trip, while towing a trailer, this is about the only vehicle to be driving. It uses a hybrid power train, combined with advanced transmission technology to wring every last bit of energy from a drop of unleaded regular and use it for getting down the road. About the only downside, and it’s considerable, is the monster MSRP of $50,490. That’s for the 2-wheel drive version; you’ll pay more to deliver power to all the wheels, should you want to.

The new Hybrid Tahoe is really expensive, but if you need the combination of this much size and towing capacity, nothing else makes the list while delivering anywhere close to this kind of fuel economy, especially if you do much of your driving in urban areas. In stop and go driving the hybrid power really comes into it’s own and saves gas. It comes with every option under the sun, and if you check all the boxes, you can rapidly find your bank account depleted by an even larger sum, so exercise some restraint.

Until next time………..

It’s true. Well, the easy part is a total fabrication, but if you can design and build a 100mpg car that people actually want to buy, you could win the $10 million automotive x-prize. It is the automotive version of the x-prize that got (well funded) private citizen groups everywhere scrambling to be the first into space in their own vehicle.

The Anasari Foundation what worked so well as a technology driver for space vehicles could spur innovation for those on terra firma as well. It’s not as easy as it sounds. You can’t just take a racing bike with a lightweight faring, put the most fuel efficient engine you can find on it, and go pick out your yacht. Anyone with half a brain could pull that off.

No, the foundation has much more difficult criteria one must meet before they get to make their banker’s day. There are actually 2 categories, but the one with the most dough requires that your car must carry 4 adults, meet federal safety and emissions standards, and (here’s the tough part) be a car that consumers would actually want to endure an afternoon at the dealership enough to purchase with their own money.

Consumers are a demanding bunch for the most part. They’ll want a car that goes and stops much like any other, although I’ll bet they’ll make a few concessions to reach the century mpg mark. If gas should go much past $5.00 a gallon, you’d probably find enough drivers willing to give up A/C and power windows that you could actually market about anything that got 100mpg.

One more thing – Performance is essential, because the $10 million prize will go to the fastest car that meets the specifications.

Here’s my plan for the 100mpg car:

100mpg Powertrain:

• ½ liter, common rail turbo diesel-electric hybrid.

When running, the tiny, high-pressure rail turbo diesel is always working at its most efficient rpm range. It only charges the batteries. The drive wheels are powered entirely by a high efficiency electric motor.

• Regenerative braking to recapture energy
• Advanced Li-Ion battery pack

100mpg Chassis:

• Carbon fiber monocoque construction – lightweight and strong
• Lightweight is of the essence to reach 100mpg and have good acceleration, so the design goals would be to keep weight as low as possible.
• Target weight – 2,200lbs. wet, less passengers
• Innovative technologies will be used to keep weight low, such as active noise cancelling to minimize interior noise, rather than using heavy sound deadening. No one will buy a vehicle without a sound system anyway, so it can serve two purposes.

Performance Targets:

• 0-60mph – <10 seconds
• An 83 hp motor should be required to be less than 10 seconds to 60mph and equal the Toyota Prius ¼ mile ET and terminal velocity with a 2,200lb weight and a 150lb driver aboard.

I’ll leave it someone else to fill in the details. I’m sure greater minds than mine are hard at work on this project already.

The Chevy electric car, or more properly, the new Chevy Volt plug-in hybrid, and the similar cars its’ success is sure to spawn, is the best chance the General has to return to profitability after an especially bleak quarter. Even GM can’t absorb too many -$15 billion quarters and expect to survive. To be fair to GM, some of this can be attributed to non recurring events and write downs, that aren’t likely to be repeated.

As a manufacturer built on the success of relatively fuel inefficient vehicles, such as the Silverado and Tahoe, GM needs alternatives that consumers want to by with the same fervor that they flocked to lots with when gas was $1.80/ gallon and new Tahoes had dealer incentives. With gas hovering at $4.00 per, those days may never return, but GM’s hoping that a new era of profitability returns, driven by $30,000+ plug-in hybrids.

$30,000+? Yes, the initial versions of the Volt promise to carry a fairly robust price tag. Don’t for get that fuel efficient vehicles will continue carry with them some pretty attractive tax incentives. Unfortunately the $30,000 price for the first versions of the Volt likely factors those tax benefits in already. The actual price is closer to $40K! Now, if you’re Leonardo DiCaprio, that’s no big deal. For those of you that get your paychecks from Paramount Sand and Gravel, Paramount Landscape Services, or Paramount Electric, rather than Paramount Pictures, the Volt’s price may be a bit of a stretch.

If Chevy can just get the Volt to have the same cachet among the ultra green set as the Prius enjoys, the same automaker that draws ire and wrath for daring to concoct the Tahoe / Suburban will ironically be lionized for popularizing the plug-in hybrid.

One thing’s for sure, it will take more than $4 or $5 gasoline to make the Volt a success. Chevy’s marketing department had better do a bang-up job. After all Toyota will be hot on their heels with the plug-in Prius. The Volt promises a higher level of technology than the Prius, and will be larger, theoretically appealing to those with larger (Suburban sized?) families.

The Volt will face stiff competition in the marketplace when it arrives however. Besides the aforementioned Prius plug-in, Honda is readying a few possible competitors, such as a hybrid version of the already economical Fit, a “Global Small Hybrid”, and the new CR-Z, being referred to by some as the “CR-X for the 2010’s”. All will feature hybrid power trains and outstanding fuel economy. Nissan also has electric cars just around the corner, having announced them in May of this year.

The question is weather or not Chevy’s “electric car” (it can go up to 40 miles on electric only power), as they like to call it, will rise above the competition and generate sufficient sales and profits to pull GM out of its doldrums. GM may be able to generate substantial licensing revenues from some of the technologies it’s developed for the new car and its E-flex drive train. GM has substantial engineering might, and has developed some of the things we take for granted in cars today, like another electric enhancement to our rides, the electric starter.

It’s already reportedly talking with rival Ford to use some of the power train. How long will the batteries in the Volt last? GM is saying that they expect a 10 year battery life, which is a good thing, considering the initial cost of the advanced lithium ion battery pack. Priced a replacement lithium ion battery for your laptop recently? Now you see what I mean.

So, although the Chevy electric car may be a paragon of modern technology, and may in fact help the General return to profitability, it will not be a cheap car for the masses, which may be okay, since they’ll only build about 10,000 units the first year, and could probably sell them all, even at $40,000. If the price of gas remains above the magic $4.00 per gallon barrier, or people expect it to, the Chevy Volt will be a slam dunk for GM.

If the price of gas should decline to around $3.25, and people expect it to stay there, the less expensive traditional hybrid alternatives will be much more attractive to car buyers, especially given the rising price of electricity.

Until next time, save that gas, you’ll need it.
