C&D finally tests the LCI X7 40i -- Glowing Review: "Six Is Enough"

BIMMERPOST
     Featured on BIMMERPOST.com
Pretty glowing review from C&D. I've been waiting to see their test figures to see how the acceleration figures compare to the pre-LCI 40i given the bump in HP and Torque.

"Winces at the sight of potholes."

The 23's especially with that width of tire seem like such a weird choice. 285/325 make so much more sense as there are multiple brands running that.

Reminds me I need to take some pictures of my 23's and sell them...

Yeah as good as the larger wheels look.... I ended up sticking to the 21" base wheels because 1) my wife likes to aim at curbs rather than avoid them and 2) I like my X7 to be more about comfort and luxury than about sportiness

um.. wow.

"Actually, this X7's acceleration also calls to mind BMW's sporty coupes and sedans. The 4.6-second 60-mph time betters that of the 430i xDrive coupe (5.2 seconds) and the last 540i we tested (4.7 seconds). The SUV's 13.4-second quarter-mile sprint at 102 mph puts it within spitting distance of that same 540i. Against rival SUVs, the X7 40i is quicker than the six-cylinder Mercedes GLS450 and the Audi Q7 with the turbo 3.0-liter V-6. Even so, the xDrive40i still trails a respectful distance behind its V-8 sibling the X7 M60i, which blazes to 60 mph in 3.8 seconds and rips through the quarter-mile in 12.3 seconds at 111 mph."

prior car was a chipped X3 M40i and i didnt think the X7 40i felt sluggish compared, definitely not the quoted 5.8s

this is interesting:
Abetted by the optional four-wheel steering, the X7 xDrive 40i also exhibits excellent lateral stability around the skidpad, where it hangs on with 0.92 g of grip—that absolutely stomps the Range Rover Sport (0.81 g), not to mention the racier X7 M60i (0.85 g). Defying its 5545-pound curb weight, this SUV also stops from 70 mph in just 149 feet, outbraking both the M60i (155 feet) and the Audi RS Q8 (158 feet); it also stops shorter than the Lamborghini Urus Performante (152 feet).

i wonder if the M60i had all seasons on
the slight weight difference between the i6 and V8 shouldn't make for that much of a difference.

It seems like they were using the same tires. I agree it shouldn't make THAT big of a difference, but it's important to keep in mind what the roadholding skidpad represents. It's not really an indicator of overall handling... as it says nothing about weight transfer when maneuvering at high speed. It's literally just lateral grip in a constant speed/direction. So if anything, it's an indicator of how top heavy the car is (or isn't). So any added weight not towards the bottom of the car would negatively impact the skidpad rating. In this case... 300 lbs of added weight.

All this being said, I'm with you - 0.07g difference is pretty large.

4.6 seconds to 60mph is very impressive. I believe the Pre LCI B58TU was 5.5 seconds, so the LCI B58TU2 is nearly 1 second quicker from only 40hp more?

Was that a BMW quoted time or independently tested? One of the comments under the article mentioned how the LCI has a launch control feature whereas the preLCI does not.

BMW quoted 5.8, I've seen several reviews range from 5.5 to 6.2

theres some underrating shenanigans going on. my guess is its double that.

i think pre lci was quoted at 5.8 but really did it in ~5.5

"40" more hp and its at 4.6. i suspect the LCI gained some weight over the, looks like about 45lbs.

the 23" rims are not doing it any favors for acceleration either.

Hmm, it does seem there are some errors in this review. It seems they cite the 40i as having twin turbos? That is not accurate. I'm also not sure 0-60 in 4.6 seconds is accurate..

Maybe they got confused because "3.0-liter BMW TwinPower Turbo inline 6-cylinder".

Also I assume they measured the 4.6 seconds, so I am inclined to believe that part.

The twin turbo is a common mistake. Twin turbo is much more of a common phrase than "twin scroll single turbo".

As for the 0-60 time, keep in mind C&D uses a 1ft rollout in their metric. So when comparing 0-60 times from C&D you have to compare to other C&D times to maintain consistency (i.e. you can't compare a C&D 0-60 time to some other magazine's time).

yep, instrumented on the 0-60.
"At our test track, the racy-looking M60i model managed to hit 60 mph in just 3.8 seconds, but the xDrive40i wasn't far behind, hitting the same speed in just 4.6 seconds."

their other article on it has it correct in terms of the turbo- its a single twin scroll turbo. my guess is that it was a typo because of bmw's insistence on calling everything a twinpower turbo, be it a single twin scroll turbo or two individual turbos.

"The entry-level X7 xDrive40i is powered by a 375-hp turbocharged inline-six-cylinder, and the M60i has a twin-turbo 4.4-liter V-8 that makes 523 horses."

One other thing i'd note, and i'm sure many of you would agree: the ride on 21"s is absolutely fantastic. It feels somewhat unfair (but understandable) that they used 23"s a a baseline test in this review.

Having daily'd a RR Sport, Defender, Grand Cherokee L, Q8, Cayenne - the X7 far surpasses the ride quality of all of those.

i'm rolling on 20" non run flats right now and the ride is very plush. i rode in a newer escalade (uber) the other day and was surprised at how much harsher the ride was, even compared to my 22" summers

Most of the vehicles used by professional reviewers have Dynamic Handling Package. I wonder what their review would have been if the vehicle didn’t have DHP. Starting from last October mid the DHP is not offered on 40i.
