Can an Entry-Level Car Have 300 hp?

Vehicle Tested:
2008 BMW 1 Series 135i 2dr Coupe (3.0L 6cyl Turbo 6M)
MSRP of Test Vehicle: $39,125 Price It!!

What Works:
Powerful-engine-in-a-small-car formula; compact dimensions do indeed sharpen the reflexes; don't-look-at-me styling repels unwanted attention.

What Needs Work:
A tad more understeer than we'd like, especially on the track; BMW persists with compulsory run-flat tires and no space for a spare; don't-look-at-me styling hard to love.

Bottom Line:
Big-engine-in-a-small-car is always the right formula, especially when the pieces all come from BMW

"From here it looks like a pot-bellied pig," says Chief Road Test Editor Chris Walton as he points to the nose and scooped-out door profile of the new 2008 BMW 135i Coupe.

"Check out the overhanging character line above the taillights," we prompt. "Is this the new BMW 1 Series or a Corvair?"

You'll have to forgive us. We're taking a break from flogging BMW's 3.0-liter twin-turbocharged wünder-coupe and, frankly, we're more than a bit giddy. Three hundred horsepower and a similar dose of torque will do that to you, especially when it's in a shrunken rear-wheel-drive coupe that weighs less than a BMW 335i that shares the same engine.

E-Speak
The peerless BMW 335i has earned endless praise from us for its solid construction, balanced handling and stonking twin-turbo engine. So far it's batting a thousand when it comes to victories in our comparison tests.

But in becoming more refined, the E92 (that's BMW techspeak for 2007 and later 3 Series coupes) has gained size and weight, so its communicative responses have been muted. Well, that's what BMW fanboys will say, anyway.

That's where the 2008 BMW 135i Coupe (a.k.a. E82) comes in. Sure, when the 1 Series comes in the guise of the 2008 BMW 128i, we'd call it an entry-level Bimmer. But the inclusion of "the Engine" (as we find ourselves saying) is proof positive that BMW knows what its core enthusiasts really want.

Anti Super-Size Me
How much smaller than a 2008 BMW 335i is the new 2008 BMW 135i Coupe? At 172.2 inches, the U.S.-spec 1 Series gives up 8.1 inches of length. It's even 3 inches shorter than the E30 3 Series of the 1980s and only 0.7 inch longer than the E21 3 Series of the 1970s.

The greenhouse of the 1 Series coupe is something of a bubble, resulting in a 55.4-inch height, ample headroom and general proportions that fall between the E30 and E36 coupes. Notable deviations from the vintage BMW formula for sport sedan proportions include a higher beltline and a wider stance.

Interior space is suitably ample up front, but unless the front seat occupants are of below-average height, the rear seats are a kids-only proposition. This 6-foot-2 editor was able to travel with his 9-year-old daughter seated behind, but only just.

So the 1 Series coupe clearly doesn't share the "too big" problem of the 3 Series.

As compact as it is, the new 135i is no lightweight. It's still a full-featured premium piece, and it shows evidence of the mass that comes from 20 years of safety advances plus the "must-have" thinking about convenience features that shapes the thinking of product planners everywhere. Our test car tips the scales to the tune of 3,399 pounds, some 172 pounds less than a 335i, but still 200 or so pounds heavier than the similar-size E36 BMW M3 of the 1990s.

Cue the Bigger Hammer
But the 135i has a not-so-secret weapon that those lighter, earlier BMWs didn't have: a twin-turbocharged, direct-injected straight-6 engine that not only produces 300 hp but also packs a 300 pound-feet wallop of torque from 1,400 through 5,000 rpm.

On the road, the power delivery of the turbo six is so smooth and relentless that it makes the 1 Series fast — very fast — but never furious. This engine simply grunts it out and pulls hard from the bottom of the tach to its redline at 7,000 rpm. And the thrill quotient goes up because all this is happening in a car that's almost 200 pounds lighter than the engine's customary 3 Series package.

So the 1 Series coupe doesn't share the "too fat" problem of the 3 Series.

At the track, the twin-turbo big hammer drove our 135i down the quarter-mile in 13.3 seconds at 104 mph. The 2008 Subaru WRX STI with 5 more hp and 48 fewer pounds does the same time in the quarter-mile, but with a slower 102.4-mph trap speed.

While the STI edges the 135i's 5.0-second acceleration to 60 mph by a fraction thanks to the launch traction afforded by the Subie's all-wheel drive, the BMW ultimately has the legs at the top end and catches the STI at the finish line.

This performance does nothing to dispel our continuing suspicion that the 300-hp rating of the twin-turbo inline-6 is conservative at best.

Sometimes the Small Numbers Are Best
A shorter wheelbase gives the 1 Series a dimension of agility that the 3 Series lacks, and it measures 104.7 inches, some 4 inches less.

The suspension layout of the E82 is similar to that of the larger 3 Series. It still carries front struts with split lower arms and dual lower ball joints, while the rear retains the latest multilink layout. But both ends have been recalibrated for the 1 Series application.

Our 135i coupe came with standard 18-inch Bridgestone Potenza RE-050A run-flat summer tires: 215/40R18s up front and 245/35R18s in the back. We're still deeply skeptical about the performance of run-flats, even after the latest improvements. The mega-stiff sidewalls of the 050As disrupted an otherwise tame ride whenever we encountered abrupt, sharp-edged breaks in the pavement or even pronounced ripples.

We wish BMW would offer us the option of conventional tires or space for a spare. But since the battery resides in the trunk to help achieve a weight distribution of 52 percent front/48 percent rear, a spare has no place to live.

Ultimately, We Drive the Machine
Spirited back-road driving proves the 2008 BMW 135i Coupe can deliver the goods, as it dispatched corners with crisp turn-in, an eager willingness to change direction and impeccable grip, without sacrificing the road-worthy poise of the 335i that we love. On our test track, this translates to a blistering 72.4-mph run in the slalom, easily outpacing the last 335i we tested (69.5 mph) and edging the 2008 STI (72.0 mph). Skid pad figures are a wash, as both BMWs generate 0.89g and the STI makes 0.90g.

Understeer has been rumored to lurk within the 135i, but it didn't rear its head until we hit the road-racing track, where high-speed sweepers at the limit work the outside front Bridgestone mighty hard. Track-day junkies might want to make changes, but we think most everyone else will have no complaints.

Our 135i came with six-piston fixed-caliper brakes and 13.3-inch rotors. These calipers (something we'll see more of, our BMW sources tell us) seem like overkill when the heavier 335i and faster M3 do quite well with rather pedestrian single-piston sliding calipers. But the advantage might come in the form of consistently firm pedal feel over several days of determined street driving and extended track testing. This 1 Series comes to a stop from 60 mph in 109 feet.

It's Nice in Here
Inside the cabin, our 135i includes the Sport package, a $1,000 option consisting of an M-sport steering wheel and Shadowline trim, plus an elevated limiter for top speed. The package also includes terrific eight-way manually adjustable seats that adjust quickly, hold on tight in corners and look great. Why spend the money for optional power seats?

Handsome textured aluminum accents are applied with strategic restraint in the interior. BMW is one of a few carmakers that have figured out that accents that have the dull sheen of hand-worn metal look more upscale than any sort of chrome. And no sunlight gets reflected back into the eyes of the driver, either.

The Bottom Line
The base price for the 2008 BMW 135i is $35,675. After adding the options (including the $1,450 Boston leather upholstery) plus a $400 iPod and USB adapter and the $600 Cold Weather Package, our car's as-tested price is $39,125. And beware, because many high-cost options lurking on the options sheet can drive the price much, much higher.

It's hard to pin down the competition for the 2008 BMW 135i. On price and track performance, this test car matches up quite well with the 2008 Subaru WRX STI we tested, which costs $39,440. It matches up on performance, too. That's not bad company to be in, but at the end of the day, the Subie is no BMW.

Is the 2008 BMW 135i Coupe worth it? It depends. It's easy to go overboard with the options and jack up the price of the 135i so it no longer makes sense.

If you value a high level of steering and handling refinement and outright twin-turbo nirvana in a package that's small enough to toss around, and you can live with limited backseat space, the 2008 BMW 135i is like nothing else.

And it doesn't matter that the pot-bellied BMW 135i isn't the most beautiful car in the world. If you're doing it right, you'll be on the inside, working the steering, pedals and shifter with a huge grin on your face, happier than a pig in, well, you know.

Lead Senior Editor Ed Hellwig says:
I would find it hard to buy a BMW 135i. Don't get me wrong, it's a brilliant package — one of the best BMWs I've driven in some time. It's fast in a straight line, rips corners and is nicely finished throughout. More importantly, there's never any sense from behind the wheel that it's somehow a lesser BMW. All the materials are high quality, it seems as solid as a 7 Series and the interior feels spacious despite the small exterior dimensions. In fact, its size is often a plus when it comes to squeezing into traffic or tight parking spaces.

So why would I hesitate? Because the BMW 335i coupe is only $5,000 more. Yeah, that's not exactly chump change, but if you can afford $35K for a car, is $40K really that much of a stretch? Maybe, but I would make it. For the extra $5 grand I would get a coupe that's not only better-looking, it would lack the stigma of being BMW's "entry-level" car. Sure, the 335i coupe was the entry-level coupe until the 1 Series came along, but it never looked like it.

The only thing wrong with this car for me is the looks. I'd have to buy a 3-Series coupe to get the proper look.

for me its the opposite, I would buy 135i over 335i becuase its a better drive. the car is also not as common on the streets as a 3-series.
------------------------------------------------

135i includes M-package and Brembo brakes. 335i dont have Brembo brakes and M-package isnt included in the price. Add that to 335i and the price difference is larger than $5,000.

Thats nice.

White must be the best colour for the Coupé. It's a really nice looking car. But I dislike the orange signals on US version. Europe version look much better.

Guibo · 03-18-2008, 09:43 PM

I would take the 135i over the 335i too. I think they're about the same, in terms of looks. 335i is more classically elegant and beautiful, the 135i being more muscular/butch, yet still playing light quite brilliantly off its lines and creases. It has a purposeful, bulldog-like stance.

"stigma of being BMW's 'entry-level' car"

LOL, I've seen such snobbishness being displayed by 3 Series owners against 1 Series owners. Sadly, this will probably play out in sales performance of the 1er coupe in the US, where we already have an unfortunate "bigger is better" attitude.

Deutsch · 03-18-2008, 10:05 PM

^Not as long as gas creeps up and over $4/gallon.

Fortunately BMW will sell every last 1er coupe it brings over, because as long as people keeping buying cars based off the prestige factor and perceived positive image, and heck now this car comes in at an attainable price point, surely they'll sell.

warot · 03-18-2008, 10:23 PM

It's ridiculous how some people can look down on the 1er when they drive a car like the 3er for example... not exactly a rare car at all.

This article is yet another proof of how the 135i is not like the 335i in terms of driving dynamics. While the weight could be lower, this car just means total business if it is being compared to Sti's

Guibo · 03-19-2008, 07:44 AM

Hope you are right, Deutsch. With the weak US dollar, poor economy, and tanking BMW sales the past 2 months, I'm not so sure. Guess we'll have to wait and see.

Think this is the first test to publish comprehensive interior dimensions on the 1er coupe. Not too cramped considering the short length and inline-6. Rougly the same front & rear legroom as a V6 G37 coupe, despite being over 10 inches shorter and having a larger trunk.
Having sat in one yesterday, I felt there was perfectly adequate space for average size occupants front and rear. Only problem I'd imagine would be 6+ footers front and rear for long trips...
edmunds' subjective braking comments are pretty puzzling though. It rated only a "very good" while the G37 rated "excellent" despite the G37's longer stopping distances and noticeable fade.
