Would I Buy One?

G8-at-the-station.gif

Would I buy one? It's a question I ask myself whenever I slide behind the wheel of a car. Would I drop my hard earned money on one of these? Would I want to own it? Drive it for years? Look at it in my driveway? Tell people it's mine?

It's also the question you the reader ask me the most. So I've decided to go through all the cars we now have in our fleet and decide whether or not I would buy one. I also included a few recently departed vehicles. Seems appropriate since they just left us.

Where's the Clipboard Damn It, I Need a Car!

LT-clipboard-2.gif

What's it like working at Inside Line?

I get this question almost daily from somebody, and my answer usually blows their mind. I say, "Well, everyday this guy Mike walks up to me with a clipboard that contains a list of 15 to 30 cars ranging from a Smart to a GT-R and he says, 'Scott, what do you want to drive home tonight.'"

It's true.

The Big List of Fuel Economy

gasstation pump numbers 555.jpg

I was thinking the other day (always a dangerous proposition, I know) and wondering how all the current (or really, really recently departed) Edmunds/Inside Line long-term vehicles stack up against each other in fuel economy, at least the fuel economy we've been recording during their time with us. So I made a list. For you and for me. In case we were both wondering.

The only current vehicles missing from my list are the Audi R8 and the Dodge Grand Caravan, and that's because no one has entered any fuel data into the tracking spreadsheet for those vehicles yet. The very top and the very bottom of the list aren't going to surprise anybody (I don't think), but the middle is kinda interesting. Seeing the Rondo and the WRX so close to each other made me raise my eyebrows. Ditto the Ford GT's spot above the Veracruz. Ready to check it all out? Follow the jump with me.

2006 Lexus RX 400h: Fuel Economy Update

2006_Lexus_RX_400h.jpg

It's been a long time since we've tallied up our fuel economy numbers for this car. So here's the scoop:

Mileage: 33,944

Best tank: 28.45

Worst tank: 15.55

Average MPG to date: 20.40

That's pretty mediocre considering the EPA estimate for this model is 26 mpg combined.

2006 Lexus RX 400h: Power Outage



When I locked up our long-term RX 400h last night and noticed that the taillights were still illuminated, a little voice in my head said, "Why don't you check on that?"

"Because," I replied, "a lot of cars these days leave the lights on for a little while after you lock them. I'm sure the RX is no different."

Yeah, I should have listened to that voice. Turns out I'd left the parking lights on.

2006 Lexus RX 400h: Don't Panic!

After a long time away from it, I was pleased to be back in our long-term 2006 Lexus RX 400h this weekend. There are many things I like about it. OK, it's a little creepy to turn the key and hear. ...

2006 Lexus RX400h: Highway Fuel Economy

A hybrid Lexus in its natural habitat...oh wait

Although our Lexus RX 400h long-termer has mostly been retired from the fleet and is now driven by non-editorial Edmunds folks, it occasionally falls back into our hands to make sure everything's running smoothly with the goal to test the long-long-term reliability of hybrids. After driving the RX to and from Willow Springs International Raceway, I'm happy to report everything is A-OK.

I can't really say the same about highway fuel economy, however. With cruise control set at 75 mpg there and back, I only managed 25.4 mpg (according to the trip computer)...

2006 Lexus RX 400h: Keeping Nav and Audio Separate

Photo by Caroline Pardilla

I had our 2006 Lexus RX 400h this weekend and it's no Mini . I kid, heh. Anyway, the one thing I liked about it, apart from how aah-somely silent it is idling at a stoplight, was how the radio interface is separate from the navigation one. So I could change radio stations without having to cycle through the screens...

2006 Lexus RX 400h: 2 years and 30,000 miles

This month signifies two full years of Lexus RX 400h ownership. Our reasons for keeping it in service this long are primarily to test the durability of its hybrid system. This is also why it doesn't receive too many blog posts.

Now that we recently eclipsed the 30,000-mile mark, its about time for a fuel economy update. The numbers are unimpressive and well below 31 city and 27 hwy EPA estimations...

2006 Lexus RX400h: Sexy?





I won’t pretend I didn’t groan a bit when handed the keys to our Long-Term RX400h for the weekend. It's not that I don't like the car, but I had a dinner party to attend Sunday night. I wanted to show up in something fun, something cool. At least the Lexus would make a fine chauffeur vehicle for my Designated Driver duties...

2006 Lexus RX 400h - How Green Is My Hybrid?

2006 Lexus RX 400h

Hey, everybody, I'm green. Or am I?

EPA estimates for our 2006 Lexus RX 400h are 31 mpg city and 27 mpg highway. That's better than the average SUV and certainly better than Lexus's non-hybrid counterpart, the 2006 RX 330, which is only rated at 19 city / 25 hwy...

2006 Lexus RX 400h Pulls Garage Sale Duty

It's not all trips to the country club for our 2006 Lexus RX 400h. This past weekend, the Lexus pulled garage sale duty instead. Our friends, the Calderons, were having a garage sale and we couldn't resist the opportunity to haul over some junk of our own.

The last run consisted of just three items, a couple of Ikea wall shelves, the longest one measuring 75 inches, and a picnic basket...

Lexus RX 400h -- Strong, Silent Type

Last night I had the very good fortune to spend some time behind the wheel of our Lexus RX 400h. When I first started at Edmunds, I had a well-documented disdain for SUVs, but there have been several in the fleet that I enjoy. The Audi Q7 is super-deluxe, the RAV4 is a great little truck, the Cadillac SRX is fantastic, the FJ Cruiser could ford streams, haul tree stumps and chase down the Abominable Snowman, the Edge has... uh, .....

2006 Lexus RX 400h: 25,000-mile service

Our RX was due for a 25,000 mile service. Coincidentally the alignment was off, so we had that addressed as well.

We received prompt and friendly service when we called Lexus of Santa Monica. The service included typical visual inspections, fluid top-offs, an oil and filter change and tire rotation...

2006 Lexus RX400h: Engine braking optional

Cars without engine braking bug me.  As a result I spend much of my commute all balled up. You see, the majority of the non-shifting masses here in L.A. don't think twice about slapping down the brake pedal in 70-mph traffic. Why?..

2006 Lexus RX 400h: I Want (and Get) My MPG

Lexus RX 400h fuel mileage screen

My commute is ridiculous. It takes me between 45 to 50 minutes to travel eight miles. I could ride a bicycle home faster -- that's if there was anything resembling a safe bike lane. But my stop-and-go drive home with speeds that top out at 30 mph perhaps once, is a great laboratory for testing our hybrid Lexus RX 400h's maximum gas mileage...

Perfect Car for a Road Trip

I headed north a few days ago to interview two experts about the new plug-in hybrid developments at the Detroit Auto Show. It was appropriate that I would make this journey in a hybrid, albeit a "muscle hybrid," a 2006 RX 400h, which has recently been getting 19.9 mpg around town.

Two summers ago I took this car on a 3,000-mile trip to Whistler, Canada, and got about 26 mpg. On this shorter journey I got 24.7 mpg until I got back into Los Angeles where the reading crept up to 25.1 mpg...

Lexus RX 400h is Green, But Is It a Good Buy?

I was looking forward to driving our long-term 2006 Lexus 400h, because I own a V6 Toyota Highlander (non-hybrid), and wanted to see the differences. In addition to the expected bevvy of luxury features, the ride is so much better. Totally silient electric start leads to smooth engagement of the gas engine, enough power to play on the freeway, and a comfortable ride all the way.  By comparison, my Highlander's transmission is a loser -- it's jerky, something the dealer said is just endemic to the Highlander, so tough noogies. (Though that's probably not true of the Highlander Hybrid.)
